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.
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.

What is the difference between a cr2025 battery and dl2025?
The CR2025 is the same diameter and same thickness as the DL2025 however the DL2025 is rated at 150 mAh while the CR2025 is rated at 160 mAh. The CR2025 has the higher mAh hence the longer it can hold voltage. This makes the battery last longer. However, when shopping for a battery lately, all I could find were DL batteries.

How long should a 11.1 v 4400mAh battery last?
It depends on the load.
I am in the market for purchasing a new laptop battery. I have been looking at 9 cell batteries. But some come with 6600mah rating and others with a 7200 mah rating. What is the difference?
The 7200mAh battery will last slightly longer than the 6600mAh one. Generally speaking, the higher the mAh, the longer the battery lasts.
Which lasts longer 4400mah or 4.6ah?
This refers to a battery rating (laptop in this case) Ah is ampere-hour and mAh is milliampere-hour. A milliampere-hour is one-thousandth of an ampere-hour (3.6 coulomobs) so 4400mAh would equal 4.4Ah which means it would not last as long as 4.6Ah. Thanks Wikipedia.
How long does a 4400mAh battery last for?
That depends on the load. If the load is 1 milli-amp, the battery would last for 4400 hours. If the load is 8800 milli-amps, the battery would last for 1/2 hour. (in a perfect world, discounting electrical inefficiencies)
What battery last longer?

Which is better 1100mAh or 1500mAh?
The larger the number the longer the battery will last.
What brand of battery's last longer?
energizer
What is the difference between 4000 mAh and 4400 mAh lithium ion battery?
4400 mAh means that the battery can produce 4400 mA for one hour. Similarly, 7200 mAh means 7200 mA for one hour. In reality, these specifications are for a eight-hour rating, meaning that the 4400 mAh battery can produce 550 mA for eight hours but, comparatively, you can just ratio the ratings, so the 7200 mAh battery will last 60% longer than the 4400 mAh battery There's more to it than that, however, as you need to know that the laptop is designed to use either battery, otherwise the camparison is meaningless.
Which battery last longer in a flashlight?
duracell obv.
Why does a wet battery last longer?
The question is predicated on a foundationless premise; wet batteries do not necessarily last longer.
What car battery last the longest?
One battery is probably just as good as another, but a battery that will last longer in cold weather is the AC Delco Super Heavy Duty battery. The more cranking amps a battery has the longer it is going to last when the car doesn't want to start right away.
Which battery last the longest is it DuracellEnergizerEveready or Rayovac?
yes it does i have done a experiment and energizer last longer that duracell
