SwitchExplanation
Formula: Milliamp-hours = Watt-hours × 259.74. Why: watt-hours combine charge and voltage, so this route fixes nominal voltage at 3.85V and applies the explicit Wh = Ah × V relationship.
Watt-hours (Wh): a battery-energy unit expressing stored electrical energy at a given voltage.
Milliamp-hours (mAh): a battery-capacity unit expressing electric charge, common for small electronics and portable devices.
This route is useful when translating battery capacity into energy, or energy into capacity, at a nominal 3.85V system for comparison, planning, and datasheet reading.
This page is purely multiplicative because nominal voltage is fixed at 3.85V, so charge-to-energy scaling stays constant for this route.

Frequently Asked Questions
How is Watt-hours to Milliamp-hours at 3.85V calculated?
mAh = (Wh x 1000) / 3.85. This page fixes nominal voltage at 3.85V, so the direct answer, calculator, and table all use the same battery-energy relationship.
Why does 3.85V matter on this page?
Because charge-to-energy conversion depends on voltage. At 3.85V, the factor stays constant for this specific battery-energy route.
Can I estimate milliamp-hours from battery energy at 3.85V?
Yes. This Watt-hours to Milliamp-hours at 3.85V page is designed for that exact nominal-voltage assumption, and the mirror Milliamp-hours to Watt-hours at 3.85V page handles the inverse direction.
