How To Figure Amp Hours On A Battery. For instance if your battery is marked with a 1450 CCA it represents 200 Ah. Therefore QE V 264 12 22 Ah.

But for a rule of thumb you can divide the CCA by 725 to get the calculated Ah. BatteryStuff Tech The draw amount is what we need to calculate with. This video shows you the easy way to figure amp hours on a deep cycle or duel cycle battery.
This will assist you in deciding on the voltage you will use battery sizes and even the thickness of wires for your solar system design etc.
As youll note from the equation above The faster a battery is drained discharged the less overall amperage is available. A x H AH. For instance at C5 a battery might safely provide 268 amp hours. Battery Cycle life considerations It isnt good to run a battery all the way down to zero during each charge.
