Full charge detection occurs when observing a slight voltage drop after a steady rise. To safeguard against anomalies, such as shorted or mismatched cells, the charger should include a plateau timer to assure a safe charge termination if no voltage delta is detected.

What is float charging?

Definition: A method of maintaining a cell or battery in a charged condition by continuous, long-term, constant voltage charging at a level sufficient to balance self-discharge.

What does 72ah mean on a car battery?

The power and longevity of a battery is noted by its Amp Hour (Ah) rating. Basically, this denotes how long a battery will last if it isn’t recharged.
