What does mAh mean and how is it calculated?

mAh stands for milliampere hour and is a unit used to measure the capacity of a battery. It represents the amount of current a battery can provide in one hour.

To calculate the mAh of a battery, you need to multiply the current (in milliamperes) the battery can provide by the number of hours it can provide that current. For example, if a battery can provide 100 milliamperes of current for 5 hours, its mAh rating would be:

100 milliamperes x 5 hours = 500 mAh

So the battery's mAh rating would be 500. This means the battery can provide a total of 500 milliamperes of current for one hour, or 250 milliamperes of current for two hours, or any combination that multiplies to 500.

It's important to note that the actual capacity of a battery may be affected by various factors, such as temperature, age, and usage patterns.
