What is constant current charging?
Constant current charging is when the charger supplies a set amount of current to the battery, regardless of the voltage. This stage is used to overcome any internal resistance in the battery so that it can be charged as quickly as possible. After the initial constant current stage, the charger then switches to a constant voltage mode.

Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage.
How do you charge a battery with a constant voltage?
The constant voltage method of charging batteries is one of the most common and simplest methods. It involves applying a constant voltage to the battery, typically around 14.4V for lead acid batteries, until the current flowing into the battery drops to a very low level.
