How to calculate battery bank energy
This calculator finds battery bank energy capacity in watt-hours by multiplying voltage by amp-hours — the standard way to express total stored energy.
How the calculation works
Energy (Wh) = Voltage × Amp-hours.
Example
A 12V battery bank rated at 200Ah: Energy = 12 × 200 = 2,400 Wh (2.4 kWh).

Pro Tips for Battery Bank Energy
- Usable capacity is often less than rated capacity, especially for lead-acid batteries which shouldn't be fully discharged.
- Lithium batteries typically allow deeper usable discharge than lead-acid for the same rated capacity.
Common Battery Bank Energy Mistakes to Avoid
- Treating rated capacity as fully usable capacity, which overstates real available energy for lead-acid batteries.
