Someone I know is looking to run some equipment (a food warmer) while mobile - it pulls around 700W at 240V, which I figure is in the 60A vicinity when translated to 12V via an inverter, not including efficiency losses.
Can anyone give me a typical ampere-hour rating of a car battery, so we can figure out if it'll have enough oomph to last for a ~3 hour window ?
My thinking is to get a dedicated battery for the device and recharge it overnight, as the one in his vehicle probably isn't up to it - its a small Bedford Rascal or similar (not sure what the alternator in one of those kicks out, but I suspect he'd be stranded before long with a flat battery)
FWIW i've tried to google but had no luck - I found a couple of "select your vehicle" sites, but nothing that gives you the actual battery spec.
TIA :-}
