Image via WikipediaTo recondition your lead acid battery you will need Epsom Salt and a quart of distilled or rain water. Warm up the water to about 150 degrees (very hot but not boiling). The temperature doesn't need to be exact by any means and will still work even if the water is at room temperature, it just won't work as well. Mix 10 heaping table spoons full of Epsom Salt into the water and stir until most or all is dissolved. Then simply pour this warm solution into your battery where you would normally put water to maintain the acid levels. Do not attempt to put Epsom Salt directly into your battery because it will not dissolve into the battery acid, only water will dissolve Epsom Salt. Most batteries will be low on fluid so adding this solution will not over flow the battery. It is only recommended to add 1/2 quart of solution to an average size battery. If your battery is full of fluid already then you will need to drain some of the solution to allow for the 1/2 quart of Epsom Salt Solution. After adding the solution it is recommended to put the caps back on and shake the battery a bit to mix all the chemicals.Epsom Salt to Rejuvenate Car Battery
