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. With higher charge
To obtain maximum battery service life and capacity, along with acceptable recharge time and economy, constant voltage-current limited charging is best. To charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be
Constant voltage 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%.

The existence of the CCCV method can speed up the battery charging process with a constant current of 20% of the nominal current of the lead acid battery. To avoid overvoltage, the constant voltage method can anticipate the occurrence of damage. Utilization CUK Converter as charging can reduce output voltage ripple.

The larger the electric charging currents, the greater the effective energy stored. Larger charging current rates provoke higher temperature increases in older than newer batteries. The charging and discharging of lead acid batteries using Traditional Charge Controllers (TCC) take place at constantly changing current rates.
Discussions The charging and discharging of lead acid batteries permits the storing and removal of energy from the device, the way this energy is stored or removed plays a vital part in the efficiency of the process in connection with the age of the device.
The charging current is high in the beginning when the battery is in the discharge condition. The current is gradually dropping off as the battery picks up charge resulting in increase back emf. The advantages of charging at constant voltage are that it allows cells with different capacities and at the different degree of discharge to be charges.
