A milliamp-hour (mAh) is a measure of quality of a battery. It tells you how many hours the batter can provide one milliamp of current before it will die.
A volt is the unit of electric potential. AA, AAA, C, and D batteries are all 1.5 Volts. A 9 Volt is 9 Volts. Car batteries are 12 Volts.
AA's are typically rated in thousands of mAh. Cs and Ds are more, AAA and 9 Volts are typically less.
If you know the power that a device consumes [i.e. Remote, wireless game controller], you can calculate how long your batters will last in the following manner.
Time = [mAh / 1000] * [# of batteries * battery voltage] / device power
Ex:
Device is rated at 1W using 4 AA [1.5 Volt] batteries rated at 1000mAh.
Time = [ 1000mAh / 1000 ] * [4 * 1.5 Volts] / 1 W = 6 Hours

What difference between a kilovolt and volt?
999 Volts A Kilovolt is 1000 volts.
What is the difference between ampere and volt?
Liken volt and amp to a water in a pipe. Voltage is the water pressure in the pipe and amperage is the water flow through the pipe. They are two completely different electrical units.
What symbol is used to measure potential difference?
V which abbreviates the word volt, which is the unit of measure of the difference in electromotive force (EMF), (or electric potential) between two points of contact; the resulting voltage difference could be direct current (DC) or alternating current (AC) depending on the source of the voltage difference.
What is the relation between energy and charge?
The relationship between energy and charge is potential difference or voltage. Where a volt is defined as existing between two points in an electric field when one joule of energy is required to move a charge of one coulomb between the two points.
What potential (voltage) exists between two power supply terminals if 5 joules of energy are required to move 10 coulombs of charge between the two terminals?
Half a volt, because the energy is the charge times the potential difference.Another AnswerYou should be asking what the 'potential difference' is between the two terminals, not the 'potential'. Note that 'voltage' is another term for potential difference.
What is the difference between 1000 mah and 800 mah?
200 mah s !!!
What is the difference between 7200 mAh and 7900 mAh in rechargeable batteries?
7900 - 7200 = 700
What Is The Difference Between 802-7?

My Air soft rifle uses a 9.6 Volt 1100 mah battery can you use a 9.6Volt 2000 mah battery for a spare?
No
Difference between 12volt armature and 24 volt armature?
24 volt armature is accept balancing cut
What is the difference between a 6 volt and a 12 volt battery?
The 12 volt battery has double the electromotive force of the 6 volt. Electromotive force is measured in volts.
What is the unit of potential difference?
The unit for electric potential difference is the volt (V).
What is the unit of measure that expresses potential difference between the two electrodes in a battery?
Volt
