Specifications
- Capacity (mAh): This measures how much charge the battery can hold, expressed in milliampere-hours (mAh). Modern smartphone batteries typically have capacities ranging from 2,500 mAh to over 5,000 mAh.
- Voltage (V): This indicates the electrical potential difference the battery provides. Lithium-ion (Li-ion) smartphone batteries typically operate at a nominal voltage around 3.8V or 3.85V. Cordless phone batteries may have lower voltages, such as 2.4V.
- Watt-hour (Wh): This is a measure of total energy stored, calculated by multiplying capacity (in Ah) by voltage (V). For example, a 3400 mAh (3.4 Ah) battery at 3.8V has about 9Wh of energy.
- Battery Type: The most common type for modern phones is Lithium-ion (Li-ion). Older or cordless phones might use Nickel-Metal Hydride (Ni-MH).
- Compatibility: Batteries are designed for specific phone models or a range of compatible devices.
These specifications are usually printed on the battery itself or its packaging, although the labels in the image are not legible enough to read individual details.
