Does a 7200mAh battery last longer than 4400mAh?

Answer 1

mAh stands for milliamp hours and is a partial measure of the energy that can be stored in a battery. It is the standard used for rechargeable batteries but rarely used for non-rechargeable batteries.

The rating is only a partial measure because the voltage affects the total energy stored. For a given mAh rating, the higher the voltage of the battery, the more energy can be stored.

For two batteries that deliver the same voltage, a 7200mAh battery will store more energy than a 4400mAh one. Therefore, the 7200mAh battery should last longer.

There are other factors that affect how long a battery can last. The type of load can have a significant effect on the battery life and the condition of the battery itself.

Answer 2

A: The higher the ma hour the more power is available to do work/. mah means milli amperes per hour. The first battery will outlast the second battery by a factor of 9600 divided by 4400 or 2.18 times longer if the voltage is the same.

Answer 3

Yes, this is possible. The digits refer to the battery life as measures in milliamperehours (mAh). If "x" indicates the old battery and "y" indicates the new, then the equation (60/4200)*4400 will indicate how much longer the battery will last.
