Converting watt-hours (Wh) to milliamp-hours (mAh) is essential for understanding battery capacity and performance. The conversion formula is:

mAh=Wh×1000V\text{mAh} = \frac{\text{Wh} \times 1000}{\text{V}}

Where:

• Wh is the energy in watt-hours,

• V is the voltage in volts.

For example, to convert 2 Wh to mAh for a 3.7V battery:

mAh=2 Wh×10003.7 V≈540.54 mAh\text{mAh} = \frac{2 \, \text{Wh} \times 1000}{3.7 \, \text{V}} \approx 540.54 \, \text{mAh}

This means a 2 Wh battery at 3.7 volts has a capacity of approximately 540.54 mAh. Understanding this conversion is crucial for selecting the right battery for your devices, ensuring optimal performance and longevity. citeturn0search0
