Abstract
In accordance with various embodiments, there is a method for determining the capacity of a battery. Various embodiments include applying a predetermined current ramp to a fully charged lead-acid battery while measuring a battery terminal voltage. An Ican be determined, where the Iis a transition from charging to overcharging. A specific gravity of the lead-acid battery can also be determined. The capacity of the lead-acid battery can then be determined from the Iusing a correlation function that describes the relationship of the Ito the capacity, where the correlation function depends on the specific gravity of the lead-acid battery.
