Electric bike battery repair

If you have Magnesium sulfate (commonly known as Epsom salt) with you can easily recondition a car battery. First step is to check the battery voltage and ensure it to be less than 12 V. This shows that it is already dead. Heat about half a liter of distilled water to about 333K-348K (about 30 K below the boiling point of the water) Now, mix about a quarter of Epsom Salt in heated distilled water and stir it until the salt dissolves. For two different types of cells, this step involves different procedures.For flooded cells, you need to remove the battery cell cap.For dry cells, please drill through the sealed cap.For both the cells, pour out the old electrolyte. Insert the new electrolyte into the cell with the help of a funnel. (mainly Epsom salt + water) Next, for a flooded cell, replace the battery cap. For a sealed cell battery, plug the hole in this step. Keep in mind that you have to keep electrolyte properly distributed with no hint of air bubbles inside the cell. Finally, charge it slowly by keeping it on trickle charge overnight and then let it cool. By morning, you have a reformed cell in your hand that performs as good as new!
