12V Battery FAQ
-
How long will a 20Ah battery last?
If a battery is rated at 20Ah capacity at 20HR, it means that the battery can discharge 1 Amp per hour over that 20 hour period. A High Rate Battery will typically be rated at 10HR or less.
-
How long can a 12V battery run a TV?
On average a standard car battery will be able to power a TV for around 10 to 20 hours.
-
Does Ah affect battery life?
In a broader sense, the amp hour rating does tell us a little bit about the battery’s capacity. For instance, a battery with a 10 Ah rating will last twice as long as a battery with a 5 Ah rating when used under similar conditions, but it does not mean that it will actually last 10 full hours.
