Cycle life is based on the depth of discharge (DoD). ... How to Measure State-of-charge BU-904: How to Measure Capacity BU-905: Testing Lead Acid Batteries BU-905a: Testing Starter Batteries in ...
Each cell produces 2 V, so six cells are connected in series to produce a 12-V car battery. Lead acid batteries are heavy and contain a caustic liquid electrolyte, but are often still the battery of choice because of their high current density. The lead acid battery in your automobile consists of six cells connected in series to give 12 V.
