We look at caring for car or tractor lead-acid batteries over the winter and rejuvenating or reviving them if they appear dead after a period of disuse. Possible methods of doing this include the much reported use of baking soda and Epsom salts, but also the use of sulfuric acid when trying to charge a dead battery, and also use a higher than normal charging voltage such as what is often available from old style dumb battery chargers. --------------------------------------------------------------------------------------------------------------------------------
