During discharge, both plates convert to lead sulfate (PbSO 4) and the electrolytes becomes less acidic. This reduces the specific gravity of the solution, which is the chemical "state of charge" of the battery. This causes the voltage to drop in each cell because the voltage is dependent on the differential between the plate materials and the strength of the acid. During discharge, the ...

In sealed lead-acid batteries (SLA), the electrolyte, or battery acid, is either absorbed in a plate separator or formed into a gel. Because they do not have to be watered and are spill-proof, they are considered low maintenance or maintenance-free. SLAs typically have a longer shelf life than flooded batteries and charge faster. However, they can be more expensive.
