A trickle charger is a battery charger for cars that are designed to be left on for an extended amount of time to recharge the battery.

It slowly charges the battery and prevents the regular depletion of charge that batteries experience.

Because various people have different ideas about how long a trickle charger should be left on a battery, numerous versions have been created.

Some trickle chargers can be used indefinitely on a battery. These might be used on a vehicle that is not used frequently or that is stored for the winter or summer.

In the event that the vehicle is needed in an emergency or other unexpected situation, a trickle charger constructed expressly for this is left on.

It prevents the battery from being exhausted due to inactivity.
