How To Restore A 12 V Car Battery

If you would like to recondition your car battery, the steps aren’t difficult. Because the battery is large and therefore the tools are easy to accumulate, you don’t need tons of your time to finish the battery reconditioning.

In fact, this easy task makes it easy to prolong the battery life, so you won’t got to replace it as often.

How To Recondition A 12v Car Battery

1.Prepare the Battery

Before you start , you want to clean off the battery terminals, but you want to wear gloves to perform this step. you’ll be handling tons of corrosion that has built abreast of the posts, which must be cleaned off before reconditioning the battery. Each battery type may need a special size and post configuration, so you would like to familiarize yourself with the varied components before getting started. Mix some bicarbonate of soda with water until it turns into a runny paste. Apply it on the posts and use your wire wool to wash the world . you’ll also use a toothbrush to wash the posts if there’s corrosion that’s difficult to wash . Don’t be surprised when the mixture foams; this just indicates that it’s working. Wash the world down with a touch more bicarbonate of soda and water. Then, wipe it off and permit it to dry completely.

2. Check the Battery Voltage

Use your voltmeter to see the battery. These aren’t expensive to get and are simple to use. Connect the voltmeter to the terminals. If it reads but 12.6V, then reconditioning might improve the lifetime of your automobile battery . If the voltmeter reads 0, the battery may need suffered a brief circuit and requires replacement.

3. Empty the Battery

If you haven’t put your goggles on yet, now’s the time. confirm they’re chemical-resistant, otherwise you could suffer burns from the battery acid. Use your screwdriver to softly get under the battery caps. If you give them alittle nudge, they ought to come off with ease. confirm your plastic bucket is nearby to pour the acid into.

As you pour the acid into your bucket, confirm the battery is usually tilted faraway from you. Take some time , so there are not any spills to affect . Once you’ve got emptied the battery cells, you’ll stand it copy as normal. Put half a pound of bicarbonate of soda into your bucket to neutralize the old acid.

4. Clean the Cells

Once the cells are empty, you would like to combine half a gallon of water with half a pound of bicarbonate of soda . Once these are mixed together, use your plastic funnel to pour some into each cell. Once they’re full, put the caps on the battery and shake it to wash out the within . The battery are going to be heavy, but you ought to do that for a few of minutes. Open the caps an equivalent way you probably did earlier and pour the cleaning fluid into your bucket. Your battery is ready for reconditioning, and you’ll safely eliminate the waste liquids.

5. Recondition the Battery

It’s time to refill the battery cells. With water and Epsom salts, you’ll create your own electrolyte. This raises the voltage and increases the amperage given to your car. It also stops the plate sulfating that kills the battery. to make your mixture, you’ll combine the Epsom salt with boiling water . the simplest thanks to do that is to feature the boiling water into one clean plastic bucket then gently add the Epsom salts while you stir.

Once the water is obvious , the electrolyte is prepared to fill the cells. Use a clean funnel and pour your mixture into each cell. Fill each cell until they’re 100% full. If there’s some leftover, you’ll reserve it for subsequent time. Put the caps on the battery and shake it again for a few of minutes. you’re able to charge the battery.

6. Charge the Reconditioned Battery

Take the caps off to make sure the electrolyte solution doesn’t overflow and warmth up. If the battery builds up an excessive amount of pressure, it can cause tons of trouble. Place your charger as distant as possible from your battery. Connect the positive cause your positive battery terminal. Do an equivalent on the negative side. Slowly charge your battery for each day and a half.

7. Test the Batter

Use your voltmeter on the battery. If you see 12.43V or more, the battery is prepared to be tested. If it hasn’t reached 12.43V yet, continue charging it for an additional 12 hours. If any of the electrolyte overflowed, confirm you fill it copy .

Remove the charger once the voltage reads normal. Place the caps back on and connect the battery to the car. Put your high beams on, but don’t start the car yet. Allow the battery to run under load for a couple of minutes. Then, use the voltmeter once more to require a reading. you ought to see 9.6V or more. If it’s reading under 9.6V, the battery isn’t fully reconditioned, and you ought to repeat the steps.

You can also cycle the battery. If it fails after the primary load test, discharge it completely and recharge it again. to empty the battery, simply put it under load by leaving the high beams on. it’d take cycling the battery four to 5 times before you get the acceptable reading. But, once you are doing , you’ve got a totally functional battery for a fraction of the value of a replacement one.
