How to figure out amp hours
WebHowever, you need to take into account voltage as well. What really matters is watt-hours. Usually, you have 120V and 5 amps which equals 600 watts; hence 600 watt-hours. Batteries don’t run on 120V; instead, most of them run on 12V. To achieve 600W at 12V, you will need 50 amps; so the draw would be 500 amp-hours (instead of 5 amp-hours). Web1 de jul. de 2013 · Once you know that, you can mathematically figure out how many amp-hours you would need for your camping battery.
