Lead acid batteries are one of the oldest rechargeable batteries since 1800s. How do they work? The principle is based on production of electricity by a chemical reaction. The Sulfuric acid in the electrolyte reacts with the Lead oxide (PbO) and Lead (Pb) to form lead sulfate (PbSO4) which is the main culprit behind wearing out of batteries over years. Lead sulfate crystallizes and the battery stops recharging. When the layers of sulfate are deposited, the battery might permanently stop. How do we bring dead batteries back? By desulfation! The reversal of sulfation allows us to extend battery life.
Establishing the connection to the battery terminals should now enable charging. If the charge current stops after 30 seconds, an activation code may be required. Some battery manufacturers add an end-of-battery-life switch that turns the battery off when reaching a certain age or cycle count. They argue that customer satisfaction and safety can only be guaranteed by regularly replacing the battery. Mind you, such a policy also rotates inventory.
