How long does it take to charge a 12 volt battery at 10 amps?

Step 3: Charge the battery at a 10-amp rate. Take the amount of amp-hours needed by the battery and divide it by 10 amps. Using the example above, it would take around 4.5 hours to recharge that battery. (The best charger to use to charge a car battery is a 3-stage automatic 12 volt/10 amp charger.)

What is the best 12 volt battery charger?

Can you overcharge a battery at 2 amps?

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.

Should I charge my car battery on 2 amp or 6 amp?

In answer to your question, the six amp charger will charge your battery three times faster than the two amp charger. Six amps is stil a relatively slow charge and should be fine to use for a deep cycle battery. If your charger is telling you the battery is full, place a load on the battery before charging it.

As a rule of thumb your battery charger should be a minimum of 10% of the Ah rating of the battery. E.g A 100Ah battery would require a 10 Amp charger as a minimum. This function will allow you to use a larger charger on a small battery by reducing the output current to a safe rating.
