The Complete Guide For Learning How to Recondition Car Batteries at Home

Do you know that battery reconditioning can be a DIY job? You can follow the following steps to facilitate the process in the comfort of your home.


You will need different materials as listed below:

  • Bucket and Distilled water
  • Battery terminal cleaner 
  • Voltmeter
  • Apron 
  • Mask
  • Funnel and baking soda
  • Disposable rubber gloves and toothbrush
  • Battery charger
  • Flathead screwdriver and charger


  • Before you begin to recondition your battery, ensure that you are wearing safety attires. As a precaution, you should use a water solution and weak baking soda as neutralizing agents in case of unintended splashes and spillage.
  • Again, ensure that battery terminals are corrosion-free. You can prepare a solution of baking soda and water to the ratio of 2:1. Using the toothbrush, dip it in the same solution and rub it against the battery terminals to eliminate corrosion traces.
  • After that, take the volt reading thanks to the voltmeter. A proper terminal connection is critical at this point. The black cable should connect to the negative terminal while the red one to the positive terminal.
  • The battery will be in the right condition if the voltage reading exceeds 12.6V. You will have to recondition it suppose the readings range from 10V to 12.6V.
  • Remove the battery cap using a flathead screwdriver. Secure the battery cap in a container to prevent misplacement. Gently lift the battery and empty the electrolyte in the bucket. 
  • Never dispose of the oil battery acid solution before neutralizing it with 500g of baking soda powder. 
  • Make a baking soda and water solution in the ratio of 2:1. Meanwhile, you can open the caps and empty the solution in the previous bucket. 
  • Using Epsom salt solution, replace the old electrolyte. 
  • Using 12V/2amps slow charging mode, recharge the reconditioned battery for at least 24 to 36 hours. After that, you should read the voltage using the voltmeter. The battery will be in the perfect condition if the readings range from 12.42V to 12.6V. 
  • Last but not least, you should now perform a load test.

What Are the Right Readings for the Wholly Charged Battery? 

It should be 12.6V or more. 

Can I Overcharge My Car Battery? 

It is not right as your battery can malfunction. 

What Indicates That the Battery Is Flat Dead?

It will be flat dead if it reads at 12.0V.

Can you use a regular charger for the AGM battery?

No. It can overcharge and lead to its sudden death.
