How to Desulfate a Battery With Epsom Salts
When car batteries aren’t used for a long period of time, they lose their ability to hold a charge. Over time, the lead from the batteries’ internal plates combine with electrolytes to create lead sulfate. When this happens, you must completely desulfate the battery so that it again holds a charge. Desulfation is also known as battery “reconditioning.” Because batteries contain toxic chemicals, such as lead acid, you must take safety precautions. Always wear goggles and gloves when performing this procedure.

Things You’ll Need
Remove the Battery
Put on the gloves and safety goggles.
Ensure that your vehicle is in “park.” Open the hood by pulling the latch that’s located under the steering wheel; the latch is usually on the left side of the area under the steering wheel. Make sure that the hood stays up by connecting the hood’s adjustable rod to the rod port, if necessary.3.Read your vehicle’s owner manual to see whether the car battery has a “negative ground,” as most batteries do. Negative ground is signified by a “-” or “NEG” on the battery terminal. Positive ground is signified by a “ ” or “POS”. If the battery has a “positive ground,” disconnect this cable first. Loosen the nut and bolt on the clamp that holds that battery cable on the positive terminal. Remove the cable.Then disconnect and remove the cable to the negative terminal.4. Remove the device that holds the battery in place using an appropriate screwdriver. For example, the device may hold the battery in place using a number of Phillips-head screws. Loosen the screws using a screwdriver. Finish unscrewing the screws by hand so that you don’t lose them. Remove the battery.
