What it means
How much energy is that?
Airlines limit spare batteries to 100 Wh without approval, which is why the Wh figure matters.
The math
How to convert Ah to mAh
Charge becomes energy only once you know the voltage: Wh = mAh × V ÷ 1000. The figures below use the voltage selected above.
Example: 5,000 Ah = 5,000,000 mAh.
The table below assumes Phone cell (3.7 V). Change the voltage above and every number updates.
