Float chargers automatically shut off when the battery is fully charged.
What does float mean on a battery charger?
The Float mode follows the constant current mode. Float mode is where the battery voltage is maintained at approximately 2.25 volts per cell, or 13.5 volts for a 12V battery. This charger will maintain the battery indefinately without boiling out electrolyte or overcharging the battery.
What is the difference between a battery maintainer and a float charger?

Can you charge a dead battery with a float charger?
How do you use a float charger to charge a dead battery? Technically, when you use a float charger, you don’t charge the battery. When it’s full, then the charger is discharged from the battery. However, when the energy is low again, the charger will turn itself on and charge again.
