Before you attempt to refurbish your car battery, you should first remove the battery and check all its cells for dead cells. If any of the cells are dead, remove them and place them to one side. Next, pour 1/2 pound of baking soda into a bucket filled with the battery’s old acid. This will help neutralize the acid inside.
A battery that has been sitting for a long time is less likely to be successfully restored. This is due to the fact that batteries can lose their capacity after a period of prolonged low charge. In addition, lead-acid batteries may permanently sulfate if left low for a long time. If the battery is beyond repair, you may have to replace it.
Before you start reconditioning your car battery, make sure to use protective clothing, safety gloves, and goggles. Be sure to place a plastic bucket close to the car battery so it won’t spill. Be careful not to get too close to the battery as this can result in skin damage.
The duration of the process depends on the condition of the battery and the time you have to complete the procedure. The actual process can take an hour or two.
