Can Epsom Salt Rejuvenate a Lead Acid Battery?

Epsom salt, also known as magnesium sulfate, is a common household item often used for soaking sore muscles or as a bath additive. But can it also be used to rejuvenate a lead acid battery?

The answer is yes, Epsom salt can help to rejuvenate a lead acid battery by removing lead sulfate crystals that build up on the battery plates over time. These crystals can reduce the battery's capacity and performance. Epsom salt helps to dissolve the lead sulfate crystals, allowing the battery to regain some of its lost power.

To use Epsom salt to rejuvenate a lead acid battery:

1. Dissolve 1 cup of Epsom salt in 1 gallon of distilled water.
2. Pour the solution into the battery cells.
3. Allow the solution to sit in the battery for 24 hours.
4. Drain the solution from the battery and rinse the battery with distilled water.

After treatment, the battery should be recharged before use.

Important notes:

• Epsom salt can only rejuvenate lead acid batteries to a certain extent.
• It is not a permanent fix and will not restore the battery to its original condition.
• Epsom salt is not suitable for use on other types of batteries, such as lithium-ion batteries.
