ez battery reconditioning – All Steps in 1 by Walt Barrett Made in USA

all right these are the tools that we use to recondition batteries we need safety glasses a plastic funnel a battery hydrometer a battery post cleaner a common screwdriver a voltmeter with probes on it these are the probes a battery low tester and the chemicals that we add this is how we use a battery post cleaner you'll notice it has wire brushes up inside it you place it on the post turn it several times remove it and then go to the next post push it on turn it several times and remove it that gets rid of the corrosion and dirt off the sides of the post the first thing you do is to check the voltage of the battery before you do anything else if the battery doesn't read at least 12 volts you've got a problem with one of your cells and the next thing you should do is check the cells to see if one of them is dead this is how you remove the battery caps you take a common screwdriver catch it under the edge pry up go to the other side if you have to and put them out of your way now that we have the caps off we can proceed with the cell test this is how we test the cells we have these probes that we've made from coat hanger wire they're expendable when they get corroded out you just throw them away and make new ones you just clip them onto your voltmeter and then you place this is how you start off you just clip them onto your voltmeter and then you start with the positive terminal and you put your cable on it and you go to the first cell and you get a reading of 2 volts then you go with the positive cable to the first cell and then to the second cell and you should get a reading of 2 volts then you keep going down the battery positive negative positive negative positive negative positive negative you must get a reading of at least 2 volts for each cell or you've got a week or a bad cell all right now we're going to do a battery load test and it's important how you hook this up to the battery you always take and hook up the positive lead first and the negative lead last that's so you won't make any spots and have an explosion now I'm going to set the meter up on top of the battery so you can see it properly you'll notice that it's reading in the high green it's reading 13 volts now what we're going to do is we're going to do the load test there's a switch on the bottom of the load tester that puts a load on the battery it heats up a heating coil which is behind this will you when I put the switch on you're going to see the meter drop now what you would do is you would count 10 seconds by going a thousand one a thousand two that set you till you get to a thousand ten very slowly you'll feel the heat coming out of the grill here and then when you let go of the switch well there's two things you want to know first of all you notice that Billy dropped down into the yellow second is when we let it go it goes right back up to about 13 volts again so that means the battery is really in very good shape this particular battery so that's how you use a load testing now when you take it off you always take off the ground first you do it opposite then going on and take off the positive last again so you won't make any sparks now we're going to explain the battery hydrometer to you the battery hydrometer is a glass tube with a suction bulb on it that draws the electrolyte from the battery up into the glass tube until the float inside begins to float now when the flow is flowing it has markings on you can see a red strip from there to there a narrow white strip and then a little wider green strip now how does that work well if it floats up and it's in the green that means the battery is in pretty good shape the more that the float sticks up out of the electrolyte in other words if it's down in here somewhere the stronger the battery is if it only floats up into the white that means the battery is only in fair shape and if it goes up into the red then it really needs a charge so what we're going to do now is we're going to do a couple of sample tests just so that you can see how this works this is the actual test you place the hydrometer down in the cell until it touches the top of the plates you squeeze the ball hard as you can get all the air out of it then draw the electrolyte up into the glass cylinder now you see the float is floating already so you can stop right there hold it level and let it float now you notice that it's just at the top of the green almost into the white so obviously that's an indication that the battery needs some charging because the specific gravity of the electrolyte is low all right now remember this fluid is called electrolyte and it's a mixture of sulfuric acid and water it's very dangerous you don't want to get it on your clothing now we put it all back in the sub and the prep procedure is to read each cell the same way now you'll notice that this cell is a little stronger these are more of the green showing we put that one back it still needs to charge this also is a good way to test the cell if you don't have a voltmeter to see if it holds 2 volts obviously if it's a bad cell it's not going to give you a very good reading on the hydrometer so the hydrometer is another way to see what condition your cells are in now this one's about the same as the one we just did it's at the top of the green again indicating that a charge is needed while you're doing this you should also check the level of the electrolyte inside the battery and that level should be at least an eighth of an inch above the top of the lead plates all right now once we've determined that this battery is available for reconditioning it's time to add the china Depot battery reconditioning chemicals and this is how we do it we take a plastic funnel and a tablespoon and we get a heaping spoon and we start with the first salt we add it very dry so it goes in easily then we go to the next cell no the heaping spoon and then to the third cell right on down till we've done all the cells in the battery we don't have to be too fussy you get to the last cell and we're all set okay now that we've added all the chemicals we're ready to put this battery on the charger and it'll be on for about 24 hours and then we should have another perfectly reconditioned battery and again we're using the China Depot battery reconditioning chemicals it's our own formula we've used it for about 25 years thank you very much
