How long can you leave a trickle charger on?

What happens if you leave a car battery charger on too long?

A: If you leave the charger connected continuously, even at a mere 2 amps, the battery eventually will die. Overcharging a battery causes excessive gassing — the electrolyte gets hot and both hydrogen and oxygen gas are generated. On sealed batteries, the buildup of gases could cause the battery to burst.

Can you overcharge a 12 volt battery?

A 12V lead-acid battery will not be damaged by overcharge if the voltage is kept low enough to avoid electrolysis, and the charging current is kept below 0.2C (5 times less than the Ah capacity). If it can put out more current than the battery can take then the battery may overheat.

What amp trickle charger do I need?

The main thing that defines any given charger as a trickle charger is that it will either have a low amperage option, or it will only be capable of putting out a low charging amperage. Most trickle chargers put out somewhere between 1 and about 3 amps, but there is no hard and fast rule on that.
