Theoretical load of a lead-acid battery

graphique fonctionnement batterie plomb

The theoretical load of a lead battery is carried out in 3 phases 

Phase 1: The current is limited to a rate of about 1/5 of the nominal capacity. The tension increases gradually until you reach its maximum threshold regulated 2, 35V/elements.

Phase 2: The load voltage is regulated at 2, 35V/elements, the load current decreases so until becoming less than C/100. The battery is charged at the end of this phase.

Phase 3: Once the battery is charged, it enters mode (Floating) trickle charge to keep it at 100% load. The voltage applied to the battery will be around 2, 26V/elements.
