The lead-acid battery mainly uses two types of charging methods namely the constant voltage charging and constant current charging. It is the most common method of charging the lead acid battery. It reduces the charging time and increases the capacity up to 20%. But this method reduces the efficiency by approximately 10%.
This is the conventional charging technique for charging the lead corrosive battery. The battery is charged by making the current consistent. It is a basic technique for charging batteries. The charging current is set roughly 10% of the greatest battery rating.
Using rest periods and high pulsed current is reducing the risk of thermal runaway and grid corrosion. It is a new technique for battery charging. The main emphasis is on prolonging battery life. Sulfation is the major motivator that will destroy the battery entirely. The technique was developed from this perspective (Praisuwanna and Khomfoi 2013).
Charging of lead–acid cell Discharging of a lead–acid cell The chemical reaction takes place at the electrodes during charging. On charge, the reactions are reversible. When cells reach the necessary charge and the electrodes are reconverted back to PbO 2 and Pb, the electrolyte's specific gravity rises as the sulfur concentration is enhanced.
According to recent research, the failure mode of lead–acid batteries is PAM weakening and shedding, and the battery lifespan is primarily confined to the positive electrode. As a consequence, the lead–acid battery has hit a stumbling block that must be addressed to improve the PAM of the lead–acid battery's efficiency.
Under the right temperature and with sufficient charge current, lead acid provides high charge efficiently. The exception is charging at 40°C (104°F) and low current, as Figure 4 demonstrates. In respect of high efficiency, lead acid shares this fine attribute with Li-ion that is closer to 99%.

Lead Acid Battery Voltage Chart
When charging a lead-acid battery, there are three stages: bulk, absorption, and float. During the bulk stage, the battery is charged at a high current rate until it reaches 80% to 90% of its capacity. The absorption stage then follows, where the battery is charged at a lower current rate until it reaches 100% capacity. Finally, during the float stage, the battery is …
