Hi friends,
I am having a little difficulty understanding how amp hours being pulled from a battery are calculated, any help would be much appreciated!
I have a 12v 125Ah deep cycle battery. Research has told me that for DC appliances you divide their wattage by 12V to give the amps, so for example a 24W DC item would be at 2A and thus with the 125Ah battery would last 62.5 hours?
My question, however is how does this work when an inverter is used? for example I have a 24W AC appliance that I wish to know how long will operate with the battery, is it still a case of dividing the wattage by the battery's voltage or is there more to it than this?
Thanks,
Tina
