The cut off circuit automatically cuts the charger from battery.
It protects the battery from overcharging..
Can a battery explode if overcharged?
When overcharged, lithium ion batteries may overheat, explode and cause fires. Even slight overcharging reduces a cell’s discharge capacity, leading to overdischarging, which increases impedance and heat generation, and decreases cell lifetime.
Can you overcharge a battery with a trickle charger?
Trickle Chargers Left Unattended If left unattended trickle chargers can overcharge a car battery by charging the battery above 12.6 volts. … If the battery voltage drops below a certain threshold the battery charger will turn back on and charge the battery until it is fully charged again.
