The runtime of a 2200 mAh battery depends on the power consumption of the device it powers. To estimate battery life, divide the battery’s capacity (2200 mAh) by the device’s current draw (in milliamps). For example, if a device consumes 500 milliamps per hour, the 2200 mAh battery would last approximately 4.4 hours (2200 mAh / 500 mA = 4.4 hours).
