Sealed Lead Acid Batteries Technical Manual Version 2
3.3 Battery Self-discharge The lead acid battery will have self-discharge reaction under open circuit condition, in which the lead is reacted with sulfuric acid to form lead sulfate and evolve hydrogen. The reaction is accelerated at higher temperature. The result of self-discharge is the lowering of voltage and capacity loss.
8. Battery capacity and Peukert exponent
Lead acid are more affected by this than lithium batteries are. The battery monitor takes this phenomenon into account with Peukert exponent. Discharge rate example. A lead acid battery is rated at 100Ah at C20, this means that this battery can deliver a total current of 100A over 20 hours at a rate of 5A per hour. C20 = 100Ah (5 x 20 = 100).
