Safety always comes first and remember that it is important to follow the reconditioning instructions carefully.
Here are the ways on how to recondition a car battery at home:
- Create a mixture of baking soda and water. You will need this solution in case of any potential spills or splashes occur.
- Remove corrosion in the battery terminals. You can do this by using a wire brush dipped in the baking soda and water solution. You can also use sandpaper grit if this is available but be very careful as it may cause more damage or create sparks.
- After cleaning the corrosion, use a voltmeter to measure the voltage of the battery. Make sure that the jumper cables are securely connected to the jump leads on either side of your battery and is not loose. The voltage reading will tell you if it will proceed or if the battery has to be replaced. Proceed to the following procedure if the reading is between 10V to 12.6V. Booster cables are not needed if the voltage reading is between 12.0V to 14 volts.
- Remove the old electrolyte from the battery and refill it with a baking soda solution. Gently shake the battery for about a minute and then drain the solution out.
- You are now ready to replace the old electrolyte with an Epsom salt solution. Mix the Epsom salt with water and then pour it into the battery hole. You can also use a funnel or small syringe if you prefer but make sure that there are no bubbles left at the top of your battery before putting back the caps then move to the next step.
- Connect the reconditioned battery up with a 12V power supply and slowly charge it at 2 amps. This will usually take around 24-36 hours. After charging your battery, use a voltmeter again to recheck the voltage. The reading should be between 12.42V-12.6V for an excellent condition battery. You can test for battery life using a load tester. If the voltage is still at 9.6 volts after 15 seconds of testing, your reconditioned car battery is not working.
