Specifications
- <ul><li><strong>Capacity (mAh):</strong> 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. </li><li><strong>Voltage (V):</strong> 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. </li><li><strong>Watt-hour (Wh):</strong> 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. </li><li><strong>Battery Type:</strong> The most common type for modern phones is Lithium-ion (Li-ion). Older or cordless phones might use Nickel-Metal Hydride (Ni-MH). </li><li><strong>Compatibility:</strong> Batteries are designed for specific phone models or a range of compatible devices. </li></ul><p>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.</p>
