Watt hours

[Jd_]

Is this correct? Its 6:30am here n its too early to think.

A battery with 14.4 watt hour at 40 watts and one with 10.9 watt hours at 30 watts should both last .36 hours (theoretically), correct?

I know real world may vary, but is the comparison valid? That simple?

So yes?

Could be pulling this number out of thin air, but about 22 mins?

That would be to fully discharge them though I think, to 0v

So yes?

Yes.

Just divide the Wh by the W.

14.4/40 = .36

10.9/30 = .36
