How to Recondition a Car Battery That Won’t Hold Charge
There are three ways you can recondition a car battery that won’t hold charge. Fixing a car battery that doesn’t hold charge can be fixed at home with a small investment and a few tools. And there is no substitute for maintaining safety measures when refurbishing a car battery.
Here are 3 method to recondition a car battery that won’t hold charge:

- Recondition Car Battery Using Smart Battery Chargers
- Recondition Car Battery Using A 200A Charger
Method 1: Recondition Car Battery Using Epsom Salt and Distilled Water
Reconditioning a car battery using Epsom salt and distilled water is the most useful method. When you pour the mixture of Epsom salts and distilled water, it dissolves any sulfate buildup into your battery. And reviving a car battery with Epsom salt and distilled water can also make car batteries live longer.
Here are some basic requirements to recondition a car battery using Epsom salt and distilled water:
- Epsom Salt

- Trickle Charger
- Plastic funnel
Follow only the five steps below to fix a car battery that doesn’t hold charge:
Step 1: Prepare The Battery Properly
Put on the safety measure: protective eyewear and hand gloves. Clean the car battery posts by placing a battery post cleaner on each battery post.
You have to clean the battery port very precisely. Make sure you twist it back and forth until the posts become clean and bright. There is no alternative to clean and make the port bright. You have to do this first.
Step 2: Pour Out Acid From Battery
When you recondition a car battery, you have to pour out all of the acids from the battery. In automobile batteries, there are six cells, and those cells are pouring with acid.
Step 3: Mix Distilled Water And Baking Soda
After pouring out all of the acids from your car battery, you now need to make a mixture of distilled water and baking soda. Take around 250 grams of baking soda and one gallon of distilled water. Mix baking soda and distilled water until it is completely dissolved.
Step 4: Fill The Battery And Shake
Fill every cell of your battery with distilled water and baking soda mixture. Attach the battery cell caps and shake the battery strictly.
Step 5: Pour Out The Mixture Again
Now you need to pour out all of the mixtures from the battery. Make sure distilled water and baking soda mixture are completely removed from the battery cells.
Step 6: Make Epsom Salts And Distilled Water Mixture
Mix Epsom Salts with distilled water in a bowl; adding distilled water makes it liquid. If you can warm distilled water before adding Epsom salts, it will help them dissolve quickly.
Step 7: Pour Mixture Into Each Cell Of The battery
Open up the battery cell caps again and pour one tablespoon of mixture into each cell of your battery. Ensure mixture does not overfill the cells of your battery.
Step 8: Attach The Trickle Charger
In the final step of battery refurbishing, you need to attach the trickle charger to the battery. And let the battery sit for 24 to 48 hours. After 24 or 48 hours, the trickle charger from the battery. The battery should hold charge as it is new after charging the battery with a trickle charger.

Now you need to make the connection between your car battery and smart charger. Attach the red clamp of the smart charger to the battery positive terminal, and the black clamp needs to be attached to the negative terminal of your battery.
Step 3: Set Amperage Of Smart Charger
After connecting the battery and smart charger, you now need to set the amperage. Set the amperage of the smart charger at a low amp and then leave the battery to be charged for at least 24 to 48 hours. You don’t need to set the amp on the smart charger for some automobile batteries. It automatically starts.
Step 4: Disconnect The battery
The final step to rebuilding a car battery that doesn’t hold charge is disconnecting the smart charger from the battery. When the smart charger says it is fully charged, you need to disconnect the battery.

Make the connection between the car battery and 200A charger the same as the smart charger connection. Attach the red clamp of the smart charger to the battery positive terminal, and the black clamp needs to be attached to the negative terminal of your battery.
Step 2: Charge The Battery
After completing the connection of the battery and the 200A charger, you now need to turn on the charger and let the battery be charged for at least 15 minutes. But don’t charging the battery for a long 20 minutes can be the highest.
Step 3: Let The Battery Sit And Check Voltage
Let the battery sit for 1 hour completely. After 1 hour, test the battery voltage using a voltmeter. But make sure your voltmeter is compatible and indefectible. If you read less than 12.6 V on the voltmeter, you must process this charging method again.
