Frequently Asked Questions
How many mAh is 0.9 Wh?
0.9 Wh equals 243.24 mAh at 3.7V (Li-ion nominal voltage). The mAh value changes with different voltages.
How do I convert 0.9 Wh to mAh?
Use the formula: mAh = Wh × 1,000 / V. At 3.7V: 0.9 × 1,000 / 3.7 = 243.24 mAh.
Does 0.9 Wh equal the same mAh at every voltage?
No. Higher voltage means fewer mAh for the same Wh. Use the calculator above to try different voltages.
Formula: mAh = Wh × 1,000 / V. Results assume nominal battery voltage.
