How to use the Wh to Ah Converter
The Formula
Divide watt-hours by voltage to get amp-hours: Ah = Wh ÷ V. A 1,200 Wh pack at 12 V equals 100 Ah.
Practical Example
Always use the nominal system voltage your battery runs at. Lithium cells are often counted at 3.7 V per cell in marketing, while lead-acid is commonly 12 V.
