Lithium battery watt hour calculator

You may need to know the watt hour (Wh) rating of a lithium battery to determine how it should be shipped or to ensure you conform to regulations regarding air travel with lithium batteries. This applies to lithium metal batteries (disposable) and lithium ion batteries (rechargeable).

If your lithium battery does not include a watt hour (Wh) rating on the casing you can calculate it by using the voltage and mAh or Ah capacity.

Voltage:
Capacity:
Capacity Type:
Wh rating:
