AA and AAA rechargeable batteries typically range from 500 mAh to 3000 mAh capacity. Lower capacity batteries around 500-1000 mAh are cheaper but don't last as long per charge. Higher capacity batteries around 2000-3000 mAh cost more but provide longer runtime. For example, a common AA NiMH rechargeable battery has 2500 mAh capacity.
For example, if a battery has a capacity of 2000mAh and a voltage of 3.7V (V), its energy capacity would be 7.4Wh or 7400mWh. This means that this battery can provide 7400mWh of energy. Conversion between mAh and mWh MAh and mWh are two different ways of measuring battery capacity, and their conversion is based on the voltage of the battery.
So a 5000mAh 12V battery stores 60 watt hours of energy. In simple terms, if you know the voltage of a battery, you can calculate how many watt hours it can provide from its milliamp hour rating. This conversion helps compare batteries of different voltages using a standard unit of energy.
For instance, if you have a 4000 mAh battery, it can provide 4 amps of current for one hour, 2 amps of current for two hours, and 1 amp of current for four hours. Though mAh is a key factor in determining the battery life, it is not the only one. Other factors include the usage patterns, screen brightness, the type of device you use, and more.
