How many hours have for a 4400 mAh?

Answer 1

To calculate the number of hours a 4400 mAh battery will last, you need to know the current draw of the device it powers. If you have the current draw in milliamps (mA), you can divide the battery capacity (mAh) by the current draw to get the number of hours. For example, if the device draws 200 mA, the battery will last approximately 22 hours (4400 mAh / 200 mA = 22 hours).

Answer 2

This is an informal unit for energy, often used for batteries. mAh = milliampere x hours. If you know how much current you will need (in milliamperes), you can divide the 4400 mAh by the amount of current, to calculate how many hours the battery will last.
