As a lead-acid battery is charged in the reverse direction, the action described in the discharge is reversed. The lead sulphate (PbSO 4) is driven out and back into the electrolyte (H 2 SO 4). The return of acid to the electrolyte will reduce the sulphate in the plates and increase the specific gravity.
If we break the name Lead Acid battery we will get Lead, Acid, and Battery. Lead is a chemical element (symbol is Pb and the atomic number is 82). It is a soft and malleable element. We know what Acid is; it can donate a proton or accept an electron pair when it is reacting.

According to Battery University, the less you allow a Lithium-based battery to discharge before charging it again, the less wear it will undergo and therefore the longer lifespan it will have.(e.g. discharging to 40% before charging is better than discharging to 0% before charging). Similar to a mechanical device that wears out faster with heavy use, the depth of …

Fully discharging a lead-acid battery can damage its health and shorten its lifespan. Unlike some batteries, lead-acid batteries do not have a "memory effect." However, deep discharges negatively affect voltage levels and overall battery performance. To optimize battery life, it''s best to keep the battery charged.
In addition to the depth of discharge and rated battery capacity, the instantaneous or available battery capacity is strongly affected by the discharge rate of the battery and the operating temperature of the battery. Battery capacity falls by about 1% per degree below about 20°C.
Yes, discharging a lead acid battery can cause damage. Frequent deep discharges can shorten the battery''s lifespan. Lead acid batteries are designed to work optimally when they are not fully discharged. When discharged below a certain voltage, sulfation occurs.
