Lead acid charging uses a voltage-based algorithm that is similar to lithium-ion. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries.
Test show that a heathy lead acid battery can be charged at up to 1.5C as long as the current is moderated towards a full charge when the battery reaches about 2.3V/cell (14.0V with 6 cells). Charge acceptance is highest when SoC is low and diminishes as the battery fills.
Experiments on a 12 V 50 Ah Valve Regulated Lead Acid (VRLA) battery indicated the possibility of 100 % charge in about 6 h, however, with high gas evolution. As a result, the feasibility of multi-step constant current charging with rest time was established as a method for fast charging in lead-acid batteries.
The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage charge methods, the charge time can be reduced to 8–10 hours; however, without full topping charge. Lead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid Systems)
The charging process of a lead-acid battery involves applying a DC voltage to the battery terminals, which causes the battery to charge. The discharging process involves using the battery to power a device, which causes the battery to discharge.
Lead acid batteries must always be stored in a charged state. A topping charge should be applied every six months to prevent the voltage from dropping below 2.10V/ cell. With AGM, these requirements can be somewhat relaxed.
