Step-by-Step: DIY Car Battery Reconditioning

If your car battery is dead or showing signs of weakness, don’t rush to the store for a replacement just yet. Many people are surprised to learn that most lead-acid car batteries can be reconditioned at home using simple tools and techniques. Reconditioning your car battery not only saves money, but it also extends the life of your battery and helps reduce environmental waste. In this step-by-step guide, we’ll show you how to recondition a car battery safely and effectively.

1. Understand What Battery Reconditioning Is

Battery reconditioning is the process of restoring the lost performance of a lead-acid battery by reversing the chemical breakdown inside the cells. Over time, lead sulfate crystals build up on the battery plates, reducing capacity and charging ability. Reconditioning involves cleaning these plates and restoring the electrolyte balance, often reviving a battery back to 70–90% of its original capacity.

2. Know Which Batteries Can Be Reconditioned

Before starting, it’s important to identify whether your battery is a candidate for reconditioning. Traditional flooded lead-acid batteries (the kind with removable caps) are the most suitable. AGM and gel-type batteries are more sensitive and may not respond as well. If your battery has visible physical damage, like cracks or leaks, it should not be reconditioned and must be recycled instead.

3. Gather the Necessary Tools and Materials

You’ll need safety goggles and gloves, a flathead screwdriver, distilled water, baking soda, Epsom salt, a funnel, a toothbrush, a battery charger, and a plastic container. Always work in a well-ventilated area away from open flames.

4. Inspect and Clean the Battery

Remove the battery from the car. Use a dry cloth to wipe the casing clean. Mix a solution of baking soda and water (1 tablespoon to 1 cup) and scrub the terminals with a toothbrush to remove corrosion.

5. Test the Battery Voltage

Use a multimeter. A healthy 12-volt battery should read 12.6–12.8 volts. If it reads between 10.5–12 volts, reconditioning may work. Under 10 volts, results may vary.

6. Drain the Old Electrolyte

Wear safety gear. Remove the caps and carefully drain the old acid into a plastic container. Rinse each cell with baking soda and distilled water to neutralize and clean.

7. Prepare the Epsom Salt Solution

Dissolve 4 oz of Epsom salt into 1 quart of warm distilled water. This mixture will serve as the new electrolyte, helping to reduce sulfate buildup on the plates.

8. Refill the Battery Cells

Using a funnel, fill each cell with the Epsom salt solution. Do not overfill. Secure the caps once finished.

9. Charge the Reconditioned Battery

Connect the battery to a slow 12V charger. Charge for 24–36 hours. Smart chargers with reconditioning mode are ideal. Some bubbling is normal during charging.

10. Test the Battery Again

After charging, let the battery rest for a few hours, then check the voltage. Anything above 12.4V is a good sign. Optionally, perform a load test to confirm capacity.

11. Reinstall the Battery in Your Vehicle

Install the battery, clean the terminals, and secure all connections. Start your vehicle and monitor performance. If the engine starts and voltage remains stable, your battery has been successfully reconditioned.

12. Repeat the Process When Needed

Depending on the age and condition of the battery, this process can be repeated one or two more times over the battery’s life. However, every battery has a limit.

13. Practice Safe Battery Maintenance

Check fluid levels monthly and top off with distilled water if needed. Keep terminals clean and avoid deep discharges to prolong battery health.

14. Know When to Replace Instead of Recondition

If the battery case is swollen, leaking, or voltage stays low, replacement is necessary. Always recycle batteries responsibly at certified centers.

15. The Environmental and Financial Benefits of Reconditioning

Reconditioning a car battery can save $100–$200 and reduce landfill waste. It also cuts down on the energy and pollution involved in manufacturing new batteries. By learning to recondition, you help promote sustainability.

Final Thoughts on DIY Car Battery Reconditioning

Reconditioning your own car battery at home is a smart, sustainable, and cost-effective practice. With the right tools and precautions, you can restore life to your battery and delay costly replacements. If you’re looking to save money and reduce waste, battery reconditioning is a valuable DIY skill every car owner should consider.

Testing Car Batteries Before Reconditioning: Here Is My Step-by-Step Guide

Testing Car Batteries Before Reconditioning: Reconditioning a car battery can be a smart and cost-effective way to restore its performance and extend its lifespan. However, not all batteries are suitable for reconditioning. That’s why testing car batteries before reconditioning is a critical step. Without proper testing, you risk wasting time and energy on a battery that’s beyond repair. This guide will walk you through the exact steps to determine if your car battery can be successfully revived.

To test a car battery before reconditioning, start with a visual inspection for cracks or leaks. Use a multimeter to check voltage—healthy batteries read 12.6V or more. Next, attempt a slow charge to see if it accepts power. Perform a load test to check voltage under stress and, for flooded batteries, use a hydrometer to measure electrolyte health. If the battery passes these checks and holds a charge, it may be suitable for reconditioning.

1. Understand Why Testing Is Important Before Reconditioning

Before attempting to recondition any battery, it’s essential to determine whether the battery still has the structural integrity and potential capacity to benefit from the process. Testing car batteries before reconditioning ensures safety, helps you avoid unnecessary labor, and confirms whether the battery still holds enough charge or can accept one. If the battery is deeply damaged, reconditioning may be dangerous or ineffective.

2. Perform a Visual Inspection

The first step in testing car batteries before reconditioning is a thorough visual check. Examine the battery case for cracks, swelling, corrosion, or leaking fluid. Any physical deformity is a sign that the battery should not be reconditioned. Swollen or leaking batteries are hazardous and must be properly disposed of. Check the battery terminals for corrosion and ensure they are not loose or damaged. Surface-level issues can be cleaned, but major defects make reconditioning unsafe and unwise.

3. Measure the Voltage with a Multimeter

After the battery passes the visual test, it’s time to check the voltage using a multimeter. Set the multimeter to DC voltage and touch the red probe to the positive terminal and the black probe to the negative terminal. A fully charged battery should read between 12.6 and 12.8 volts. If the reading is between 12.0 and 12.5 volts, the battery is moderately discharged and may benefit from reconditioning. If the voltage is between 10.5 and 11.9 volts, the battery is deeply discharged but still has a chance to recover. Readings below 10.5 volts suggest the battery is heavily sulfated, making reconditioning more difficult and less likely to succeed.

4. Testing Car Batteries Before Reconditioning Attempt a Slow Charge Test

Next in the process of testing car batteries before reconditioning is attempting a slow charge. Use a smart charger or a manual charger with a low amp setting, ideally around 2 amps. Connect the charger and monitor whether the battery accepts the charge. If it does, this is a good sign that the internal plates are still functional. If the battery refuses to accept a charge or the voltage rapidly drops after being disconnected from the charger, it is likely beyond recovery. This step is essential because it tests the battery’s ability to hold and receive energy, a key requirement for reconditioning.

5. Conduct a Load Test

The load test simulates how the battery performs under real conditions. This is one of the most important steps when testing car batteries before reconditioning. Use a battery load tester or a specialized automotive battery analyzer. First, charge the battery as much as possible. Then, apply a load equal to half the battery’s cold cranking amps (CCA) rating for about 15 seconds. Observe the voltage during the load. If the voltage stays above 9.6 volts, the battery is likely strong enough to be reconditioned. If it drops below 9.0 volts, it indicates significant degradation, and reconditioning may not be effective.

6. Use a Hydrometer to Test Electrolyte Levels (Flooded Batteries Only)

If you’re testing a traditional flooded lead-acid battery, a hydrometer can provide additional insight into each cell’s specific gravity. This test tells you how well each individual cell is functioning. Open the battery caps carefully and insert the hydrometer into each cell. A specific gravity reading between 1.265 and 1.299 indicates a fully charged cell. Readings below 1.200 suggest the cell is weak. If one or more cells show significantly lower readings than others, the battery may be internally damaged, making it a poor candidate for reconditioning. Make sure to wear gloves and eye protection when handling electrolyte fluid.

7. Check for Internal Resistance Using a Battery Analyzer

More advanced testers can measure a battery’s internal resistance. High internal resistance reduces the battery’s ability to deliver current, even if voltage levels seem adequate. When testing car batteries before reconditioning, this is a key factor often overlooked. High resistance usually results from sulfate buildup or degraded internal plates. If resistance is significantly above the battery’s normal range (usually less than 5 milliohms for most car batteries), reconditioning may not restore the battery to functional use.

8. Evaluate the Battery’s Age

Age is another important factor when testing car batteries before reconditioning. Most car batteries last between three and six years, depending on use and maintenance. If the battery is older than five years and shows weak test results, it is often not worth the time and effort to attempt reconditioning. Newer batteries with moderate sulfation are typically better candidates for revival. You can find the battery’s manufacture date printed on a label or stamped into the casing.

9. Monitor Temperature During Testing and Charging

Temperature plays a significant role in battery performance. If a battery becomes hot during testing or while receiving a slow charge, it may have internal shorts or damaged cells. Overheating during the reconditioning process can be dangerous and is a clear sign that the battery should not be reconditioned. Always monitor the battery temperature during testing and make sure it stays within a safe range, generally under 120°F (49°C).

10. Make a Final Decision Based on All Test Results

Once all testing is complete, combine your observations to make a final decision. If the battery has no physical damage, holds a charge above 11.5 volts, passes a load test, and maintains stable internal resistance and electrolyte levels, it is likely suitable for reconditioning. However, if multiple tests show failure—especially in voltage, load, or temperature stability—then replacement is the safer and more practical solution. Testing car batteries before reconditioning helps ensure that your efforts are spent only on batteries that have a realistic chance of recovery.

Testing Car Batteries Before Reconditioning Final Thoughts

Testing car batteries before reconditioning is a step that should never be skipped. Proper testing can save you hours of work and help you avoid attempting to revive a battery that is beyond repair. It also ensures that the reconditioning process is safe and effective. By following the right steps—from visual inspections to voltage and load tests—you’ll be equipped to make smart decisions about which batteries can be brought back to life and which are ready for recycling. Whether you’re working on a personal vehicle or multiple batteries as part of a battery reconditioning business, these tests are foundational to success.

Can AGM Car Batteries Be Reconditioned? A Complete Guide

Can AGM Car Batteries Be Reconditioned? A Complete Guide

Can AGM Car Battery — Can AGM Car Batteries Be Reconditioned?

Can AGM Car Batteries Be Reconditioned?
Yes, AGM car batteries can be reconditioned if they are only lightly to moderately sulfated and show no physical damage. Using a smart charger with a desulfation mode, you can restore charging capacity by slowly recharging and breaking down sulfate buildup. However, severely damaged or deeply discharged AGM batteries are often beyond repair and should be replaced.

Absorbent Glass Mat (AGM) batteries have become increasingly popular in modern vehicles due to their durability, efficiency, and maintenance-free design. However, like all batteries, they degrade over time.
If your AGM battery is starting to fail, you might be wondering: Can AGM car batteries be reconditioned?

The short answer is: Yes, but with some important limitations.
In this article, we’ll explain everything you need to know about AGM battery reconditioning, when it’s possible, and how to do it safely.

What Is an AGM Battery?

An AGM (Absorbent Glass Mat) battery is a type of lead-acid battery that uses fiberglass mats to hold the electrolyte in place rather than letting it flow freely. This design makes AGM batteries:

Spill-proof and vibration-resistant
Able to deliver higher power output
Faster to recharge
More durable in harsh environments

You’ll often find AGM batteries in newer vehicles, motorcycles, RVs, boats, and even solar energy systems.

Despite their advantages, AGM batteries are not immune to sulfation and capacity loss — the same problems that affect traditional lead-acid batteries.

Why AGM Batteries Fail

Over time, AGM batteries experience a buildup of lead sulfate crystals on their internal plates — a process called sulfation.
Common causes of AGM battery failure include:

Deep discharges (letting the battery fully drain)
Overcharging
High temperatures
Long periods of disuse

When sulfation occurs, the battery struggles to hold a charge and deliver power. Left unchecked, it can eventually render the battery useless.

Can AGM Car Batteries Be Reconditioned?

Yes, AGM batteries can sometimes be reconditioned, but the process is trickier than with traditional flooded lead-acid batteries.

Here’s what you need to know:

If the battery is suffering from mild to moderate sulfation, reconditioning may successfully restore its performance.
If the battery has physical damage (like swelling, cracks, or leaking) or is heavily sulfated, reconditioning usually won’t work.
AGM batteries require careful charging — improper voltage settings during reconditioning can permanently damage them.

In short:

Lightly sulfated AGM batteries = Good candidates for reconditioning.
Severely damaged or deeply sulfated batteries = Better to replace.

Signs Your AGM Battery May Be Reconditioned

Before attempting reconditioning, check for these positive signs:

Voltage reading between 10.5V and 12V when resting
Battery accepts a low, slow charge
No visible swelling, leaks, or cracks
No burnt smells or severe heat during previous use
Relatively recent age (less than 5 years old)

If your AGM battery meets these criteria, you have a good chance of reviving it!

How to Recondition an AGM Car Battery: Step-by-Step

⚠️ Warning: AGM batteries are sensitive. Always wear gloves and eye protection, and use the right charger to avoid overcharging.

Step 1: Test the Battery

Use a multimeter to check the voltage.
If voltage is above 10.5V, the battery is a candidate for reconditioning.
If it’s below 10V, deep sulfation may require a specialized desulfator charger.

Step 2: Clean the Terminals

Disconnect the battery.
Use a mixture of baking soda and water to scrub corrosion off the terminals.
Rinse and dry thoroughly.

Good contact improves charging efficiency.

Step 3: Use the Right Charger

Smart chargers or AGM-specific chargers are recommended.
Set the charger to AGM mode if available.
Use a slow, low-amp charge (around 2 amps) to gently revive the battery.

Important:
Do NOT use a regular high-amp jump-start charger; it can overheat and warp the AGM plates.

Step 4: Desulfation Mode (If Available)

Some advanced chargers have a desulfation or reconditioning mode:

It sends low-frequency pulses through the battery to break down sulfate crystals.
This process can take 24–48 hours.
Monitor the battery’s temperature throughout charging.

Step 5: Recharge and Test

After a full charge, let the battery rest for a few hours.
Test the voltage again.
- A fully restored AGM battery should read around 12.8V–13.0V at rest.
You can also load-test the battery with a specialized tool to confirm performance under demand.

What If Reconditioning Doesn’t Work?

If your AGM battery:

Won’t hold a charge
Drops voltage rapidly after charging
Becomes hot during charging
Has visible physical damage

Then it’s unfortunately time to replace it.
While AGM battery reconditioning can extend battery life by 6–12 months or more, it’s not a permanent fix for severely damaged batteries.

How to Prevent Future AGM Battery Failure

Once you’ve reconditioned (or replaced) your AGM battery, use these tips to maximize its lifespan:

Keep it fully charged — AGM batteries hate being undercharged.
Avoid deep discharges — Never let voltage fall below 11.8V if possible.
Use an AGM-compatible charger — Especially important for trickle charging.
Store properly — If the battery won’t be used for months, use a smart maintainer.

Proper maintenance can help your AGM battery last 5–7 years or even longer.

Final Thoughts

So, can AGM car batteries be reconditioned?
Yes — but with caution.

If your AGM battery is only lightly sulfated and physically intact, slow and careful reconditioning can restore much of its lost performance.
However, reconditioning isn’t magic. Severely damaged, heavily sulfated, or physically compromised batteries are often beyond saving.

Always use the right equipment, follow safety guidelines, and monitor your battery’s condition closely. When successful, AGM battery reconditioning can save you hundreds of dollars and extend the life of your car, RV, or boat battery significantly.

Signs Your Car Battery Can Be Reconditioned: What You Need to Know

Can My Car Battery Be Reconditioned?
Yes, if your car battery shows a voltage between 10–12 volts, has no cracks, minimal sulfation, and still accepts a slow charge, it can often be reconditioned to restore its performance.

A car battery is one of the most vital parts of any vehicle. Without it, you’re not going anywhere. But what happens when your battery starts failing? Is it time to toss it out and spend money on a new one? Not necessarily! In many cases, battery reconditioning can bring your old battery back to life.
In this article, we’ll cover the clear signs your car battery can be reconditioned, so you can save money and reduce environmental waste.

What is Car Battery Reconditioning?

Before we dive into the signs, let’s briefly explain what car battery reconditioning means. Reconditioning is the process of restoring a battery’s original charging capacity by cleaning its internal components and replacing lost electrolytes. It often involves removing sulfate buildup, refilling the cells, and recharging the battery slowly.

Not all batteries can be saved, but many show specific signs that reconditioning could be successful.

1. Battery Voltage is Low But Not Dead

One of the most important signs your car battery can be reconditioned is the voltage reading. Use a multimeter to check the battery’s voltage.

A fully charged healthy battery reads around 12.6 volts.
If your battery reads between 10 volts and 12 volts, it likely has sulfation buildup but can still be reconditioned.
If the voltage is below 10 volts, the battery might be deeply discharged but not necessarily beyond recovery.

Tip: Batteries under 10 volts can sometimes be revived with special deep-cycle chargers or pulse chargers, although success rates are lower.

2. Slow Engine Crank

If your car engine cranks slower than usual when you start it, this is a common symptom of a weak battery. However, a slow crank doesn’t always mean the battery is dead—it could just need reconditioning.

How to recognize it:

The engine takes longer to turn over.
You hear sluggish, labored cranking noises.

A slow crank due to minor sulfation can often be corrected through car battery restoration techniques.

3. Dimming Headlights and Electrical Issues

Electrical problems such as dimming headlights, weak radio output, or flickering dashboard lights are signs of a weakening battery. If these issues happen while driving (and not just at start-up), it suggests your battery is struggling to provide consistent power.

When these symptoms appear alongside a moderately low voltage reading, it’s a strong indicator that battery reconditioning may restore proper function.

4. Visible Sulfation on the Battery Plates

If you open your battery’s caps (only possible on non-sealed batteries) and see a white, grayish buildup on the plates, that’s sulfation.

Sulfation is the number one cause of battery failure. However, light to moderate sulfation can often be reversed using desulfation methods, including chemical treatments and slow charging.

Warning: If the sulfation is extremely heavy or has caused plate damage, reconditioning may not work.

5. Battery Age is Less Than 5 Years

Lead-acid car batteries typically last 3 to 5 years under normal conditions. If your battery is within this age range, and you’re experiencing issues, it’s very likely that reconditioning could extend its life by another year or more.

Batteries older than 5–6 years are harder to recondition because of cumulative wear and tear on the internal plates.

6. Battery Case is Intact

A critical factor when deciding whether to attempt car battery reconditioning is the condition of the battery case.

Good signs:

No cracks or splits
No bulging or severe swelling
No acid leakage

Bad signs:
If the case is cracked, warped, or leaking, the battery is unsafe to handle and should be replaced, not reconditioned.

Always inspect the case thoroughly before proceeding.

7. Battery Was Not Deeply Discharged for Long Periods

Lead-acid batteries don’t like being deeply discharged. If your battery sat completely dead for months, internal plate damage may have occurred.

However, if the battery only recently discharged or sat unused for a few weeks, reconditioning could easily bring it back to working order.

Tip: The shorter the discharge period, the higher the chance of a successful battery restoration.

8. Battery Accepts Some Charge

When you connect a charger to the battery, observe how it behaves:

If the battery accepts a slow charge, even weakly, this is a good sign it can be reconditioned.
If the battery refuses to charge at all, even after several hours, the internal plates may be too damaged.

Some “smart chargers” even have a reconditioning or desulfation mode that can help gently bring the battery back.

9. No Unusual Smells

A battery emitting a strong rotten egg smell (hydrogen sulfide gas) while charging is a warning sign. It often indicates internal short circuits or severe damage, making reconditioning risky.

If you don’t notice any strange smells and the battery otherwise appears healthy, it increases the chances of a successful reconditioning process.

10. Minimal Corrosion on Terminals

Corrosion buildup on the terminals is normal with aging batteries but can interfere with charging and discharging. Light to moderate corrosion can be cleaned easily.

If the corrosion is extreme and has eaten away the terminal connections, it could affect the ability to recondition the battery. A clean battery with strong terminals is ideal for restoration.

Final Thoughts

Recognizing the signs your car battery can be reconditioned can help you save a significant amount of money and reduce waste. Batteries with low but stable voltage, minimal physical damage, light sulfation, and less than 5 years of age are prime candidates for reconditioning.

While not every battery can be saved, many just need a bit of TLC to restore their former power. Always prioritize safety, wear protective gear, and use proper reconditioning techniques to avoid injury or further battery damage.

How to Recondition a Lead-Acid Car Battery: A Step-by-Step Guide

If your car battery is struggling to hold a charge or shows signs of dying, you don’t necessarily have to replace it right away. Learning how to recondition a lead-acid car battery can save you hundreds of dollars and extend the life of your battery by months or even years. This guide will walk you through everything you need to know about car battery reconditioning safely and effectively.

How to Recondition a Lead-Acid Car Battery: A Step-by-Step Guide
To recondition a lead-acid car battery, start by cleaning the terminals and checking the voltage. Drain the old electrolyte, flush the battery cells with a baking soda solution, and refill them with a mixture of distilled water and Epsom salt. After resealing the battery, charge it slowly for 24–36 hours. This step-by-step method can revive many old batteries and extend their lifespan by months or even years.

Why Recondition a Lead-Acid Battery?

Lead-acid batteries degrade over time due to sulfation, a process where lead sulfate crystals build up on the battery plates, reducing their efficiency. Reconditioning works by cleaning and restoring the battery plates, allowing the battery to hold a proper charge again.

Benefits of reconditioning a lead-acid car battery include:

Saving money
Reducing environmental waste
Extending battery life
Improving car performance

Before starting, make sure you have the right tools and safety equipment, as handling batteries involves dangerous chemicals like sulfuric acid.

Tools and Materials You’ll Need

Safety goggles and gloves
Baking soda
Distilled water
A battery charger
A flathead screwdriver
A bucket
Epsom salt (magnesium sulfate)
A voltmeter or multimeter

Step 1: Check the Battery Condition

Before you begin the battery reconditioning process, it’s important to test whether the battery is salvageable.

Inspect the battery for cracks or leaks. If you find any, the battery is beyond repair and must be replaced.
Measure the voltage using a multimeter. A healthy, fully charged lead-acid battery should read around 12.6 volts. If the reading is between 10 and 12 volts, reconditioning may be successful. Anything under 10 volts suggests deeper issues, but you can still try to recondition it.

Step 2: Clean the Battery

Safety first! Always wear gloves and goggles when working with car batteries.

Remove the battery from your car.
Mix a solution of baking soda and water (1 tablespoon of baking soda to 1 cup of water).
Use a brush to scrub the battery terminals and remove any corrosion.
Rinse with clean water and dry with a clean cloth.

This step ensures better contact between the battery and the charger later.

Step 3: Drain the Old Electrolyte

Important: Be careful while handling battery acid. Always work in a well-ventilated area.

Remove the caps from the top of the battery cells using a screwdriver.
Tilt the battery and carefully drain the old electrolyte solution into a bucket. Dispose of the old acid according to your local hazardous waste disposal rules.

Step 4: Flush the Battery Cells

To neutralize any leftover acid:

Mix baking soda with distilled water.
Pour the solution into each battery cell.
Shake the battery gently and then drain the solution into the bucket.
Repeat this flushing process once more if necessary.

Flushing removes sulfation and leftover acidic residues, preparing the battery for the new electrolyte.

Step 5: Prepare the New Electrolyte

Instead of just water, we’ll use an Epsom salt solution to restore the car battery.

Dissolve 7 to 8 ounces of Epsom salt into a half-gallon of warm distilled water.
Mix thoroughly until the salt is fully dissolved.

This magnesium sulfate solution will help break down the lead sulfate crystals inside the battery.

Step 6: Fill the Battery Cells

Use a funnel to pour the Epsom salt solution into each cell of the battery.
Fill each cell to the recommended level.

Be careful not to overfill the cells.

Step 7: Recharge the Battery

Now comes the recharging stage:

Connect a battery charger to the battery terminals.
Set the charger to slow charge (2 amps if possible).
Allow the battery to charge slowly for 24 to 36 hours.

A slow charge is essential because it gives the magnesium sulfate enough time to react with the battery plates and break down crystal buildup.

During this time, monitor the battery closely. If you notice the battery becoming hot or swelling, disconnect it immediately.

Step 8: Test the Reconditioned Battery

After fully charging:

Measure the voltage again. A fully reconditioned lead-acid battery should read around 12.6 volts.
Load test the battery if you have a load tester available or simply install it back into your car and monitor its performance.

If the battery holds the charge and performs well under load, congratulations—you’ve successfully reconditioned your car battery!

Maintenance Tips After Reconditioning

To get the most out of your reconditioned battery, follow these tips:

Check electrolyte levels monthly and top off with distilled water if needed.
Keep the terminals clean and free from corrosion.
Avoid deep discharges; try not to let the battery voltage drop below 11.8 volts.
Charge regularly if the vehicle is not used often.

Proper maintenance can extend the life of your reconditioned battery by another 1-3 years!

How to Recondition a Lead-Acid Car Battery Final Thoughts
