According to the Battery University, a 2000 mAh alkaline AA battery contains approximately 10. 4 watt-hours, translating to roughly 39,000 to 51,840 joules of energy.
One mAh battery can deliver a continuous current of one milliampere for one hour. For example, if you have a smartphone with 2000mAh. Once fully charged, the battery can hold 2000mA. If the phone draws around 200mA per hour, it should be able to run for 10 hours.
A higher value indicates a greater ability to hold energy. For example, a battery with a capacity of 10,000 mAh can typically power a device that draws 1,000 mA for approximately 10 hours. The choice of capacity depends largely on the intended usage and the power needs of the device.
Capacity requirements: Each device has specific battery capacity needs measured in milliamp hours (mAh) or watt-hours (Wh). A smartphone may have a battery capacity of around 3000-4000 mAh, while tablets can range from 5000 to 10000 mAh. In contrast, a laptop might require a battery with a capacity exceeding 30000 mAh for a full day of usage.
Standard smartphone, tablet, and portable batteries hold 5,000 mAh of power. This rating suggests the battery delivers 5,000 milliamperes of current for one hour before recharging. A 5,000mAh battery powers a typical smartphone for a day of moderate use, including browsing the web, checking emails, and watching videos.
2,000mAh Battery: This capacity is typically found in older smartphones or small devices. For a smartphone with moderate use (calls, texts, light browsing), a 2,000 mAh battery might last 6-8 hours. For heavier use, such as gaming or video streaming, it may last 3-4 hours.
That said, a battery rated at 40,000 mAh can power a device that withdraws 400 milliamps for 10 hours. Now that you know what is mAh, let us understand the importance of mAh and how it differs from charge capacity in the following sections. mAh is the most critical factor you'll need to consider when choosing any battery-powered device.
