Recondition your Lead Battery
If you have automotives or other lead-acid batteries that you consider as scrap batteries, you may be able to recondition it; I am talking about reconditioning not battery recycling. If you follow the proper procedure, the magnesium sulfate will remove the sulfur and restore the battery to normal operating condition, though if it is totally useless for you then there is no other option than recycling batteries.
• Heat a half quart of distilled water to about 150 degrees F and add about 7 to 8 ounces of Epsom salts. Stir until the Epsom salts are completely dissolved.
• Remove the battery caps and carefully drain the water from the battery. Insert a funnel and pour enough of the Epsom salts solution in to refill the cell and repeat until you fill each cell.
• Replace the battery caps.
• Place the battery on a charger and allow it to charge slowly for 24 hours.
