I am thinking of buying a 24v 10aH battery.

if P= V*A THEN the power is 240 watts right?

because it says 10aH does this mean it can give 240 watts for
10 hours?

can it give 120 watts for 20 hours?

help appreciated

No, it's 240 Watt Hours. Theortically, 240 Watts for 1 Hour or 1 Watt for 240 Hours. Since batteries are Normally Discharged / Charged at a 10 Hour rate, we can presume that it is 24 Watts for 10 Hours, actually less than that considering an Efficiency factor.
