## How long can you charge a car battery at 10 amps?

Car batteries range from 40AH to 110AH, and alternators range from 45 amps to 200 amps.

If you are using a battery charger, a 10 amp charger will take 4 to 11 hours to fully charge the battery, a 2 amp charger will take 2-4 days.

## How long does it take to charge a 12 volt battery with a 10 amp charger?

To determine how long (in hours) you will need to charge your battery, divided 36 by 10 = 3.6 or 3.6 hours to recharge your battery. A 12 volt / 10 amp 3-stage automatic charger is the best charger for most automotive batteries.

## Can you leave a trickle charger on all night?

A trickle charger is a car battery charger designed to be left on a car for a long period of time to re-charge the battery. Some trickle chargers can be left on a battery indefinitely. These would be used on a vehicle that is not used all the time or is stored away for the winter or the summer.

## What amps should I charge my battery at?

A basic charger usually charges at around 2 amps – and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery. But there is a wide range of chargers with different charge rates on the market – from 2 to 10 amps. The higher the charge output, the faster a flat battery is recharged.

## Can you leave a battery charger connected?

No, this is safe as long as the battery is not in the charger. Some chargers may have a small power drain from being plugged in (even when not charging anything), but it shouldn’t do any damage to the device to leave it plugged in.

## How long does it take a 100w solar panel to charge a battery?

A 100 AH battery will only give you about 40 minutes at 100 amps of usage. You can use amp-hours to figure out how fast your battery will charge as well. For a 100 watt solar panel, we already know that it produces 8.33 amps. In this case, 1 amp of current flowing for 1 hour charges the battery by 1 amp-hour.
