If it has to provide 10A, the usable capacity is lower than the advertised 100Ah as explained earlier. If we add a second 100A battery in parallel, each battery now needs to supply only half of the load and thus will be able to provide the stated capacity as it is precisely the 0.05C discharge rate. Lead acid batteries need deep discharge ...
The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries.

lead–acid battery. Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles. Batteries with tubular plates offer long deep cycle lives.
Before directly jumping to know the concepts related to lead acid battery, let us start with its history. So, a French scientist named Nicolas Gautherot in the year 1801 observed that in the electrolysis testing, there exists a minimal amount of current even when there is a disconnection of the main battery.

Generally speaking, the less you discharge the battery before recharge, the longer the battery will last. Most alternative-energy systems using lead-acid chemistry and/or AGM type, are designed to keep the battery bank at least 50% or higher. I try not to let my battery bank drop below 70% (AGM batteries configured at 48v).
