The reason why lead-acid batteries discharge quickly
When a lead acid battery discharges too quickly, it can lead to sulfation, where lead sulfate crystals form on the battery plates. This process reduces capacity and shortens lifespan.
FAQs about The reason why lead-acid batteries discharge quickly
What happens if you discharge a lead acid battery?
By discharging a lead acid battery to below the manufacturer's stated end of life discharge voltage you are allowing the polarity of some of the weaker cells to become reversed. This causes permanent damage to those cells and prevents the battery from ever being recharged.
