An ampere hour (A.h) is a non-SI unit of measurement for electrical charge (the SI unit is a coulomb-which is equivalent to an 'ampere second'). So an ampere hour is equivalent to 3600 coulombs.
Cells and batteries are generally rated in terms of ampere hours, as a convenient alternative to the kilocoulomb.

What is the electrical abbreviation mAh?
milliamphere Hour or one-thousandth of an ampere-hour
How is Ampere-hour calculated if four 65 Ah batteries in series for UPS?
The ampere-hour rating of series connected batteries is the same as that for one battery, so the ampere-hour rating of four 65 Ah batteries in series is still 65 Ah. The reason for this is Kirchoff's current law - the signed sum of the currents entering a node is zero - or - the current at every point in a series circuit is the same.
Convert 216watts to Ampere Hour?
You can not convert Watts (Power) to Ampere-Hours (Amount of charge)!!! Exept if you know the voltage and the amount of time you use the power. For example: If you use P=216 W from a battery of V=12 Volts for t=1 hour, that would be: Current I=P/V=216/12=18 Amperes In time of 1 hour, you will take Q=I*t=18 Ampere-Hours from the 12 Volts battery.
What is AT and AF in MCCB?
ampere temp and ampere fuse
When did Andre Marie ampere invent the ampere?
Andre Ampere didn't 'invent' the ampere. The unit for current was named many years after the death of Ampere, in his honour. The ampere is defined in terms of its magnetic effect -i.e. the resulting force between two, parallel, current-carrying conductors. It was Ampere who discovered the relationship between current and force.
What is the electrical abbreviation mAh?
milliamphere Hour or one-thousandth of an ampere-hour
How much are 5400 Milli ampere hour in ampere hour?
There is a thousand milliamps in an amp. So it would be 5.4AH.
How much are 5400 milli ampere hour to make in ampere hour?
There is a thousand milliamps in an amp. So it would be 5.4AH.
How many amperes a 1.5 ton ac consumes in 1 hour?
I am not sure what you mean, but ampere is a unit of current, not of energy. In the case of a constant current, if the current is 1 ampere in a second, it will be 1 ampere in an hour, or in a day.
How do you compute ampere-hour?
by multiplying by resistance and dividing by voltage
How much charging ampere required for 200 apmere lead acid battery for ups 12 volt?
To find our what charging ampere to use a simple way is to divide the battery Ampere with its ampere hour (i.e. for car batteries they will say 75ah C/20) this means that the battery has 75 ampere rating based on 20 hour rating... as such to find the charging ampere divide 75 by 20 to get a charging ampere of 3.75... this is for a slow charge - to speed up the charge divide the ampere by 5 hours (to charge the battery from empty to full in 5 hours)...
How do you get ampere hour from watt hour?
Watt = ampere x volt. So if you know the voltage, you can convert amperes to watts or vice versa. If not, you don't have enough information.AnswerThe ampere hour (A.h) is a unit of measurement for electric charge (the SI unit being a coulomb). The watt hour (W.h) is a unit of measurement for electrical energy (the SI unit being a joule).In the case of cells and batteries, if you multiply its capacity (in ampere hours) by the voltage, then you'll have its capacity in watt hours.
What is definition of ah efficiency of battry?
ampere hour unit of battery
How many amps equal one amp hour?
You can't convert amperes to ampere-hours, for the same reason that you can't (for example) convert kilometers to kilometers per hour, meters to square meters, etc. Those are, quite simply, incompatible units. An ampere is a unit of electrical current; an ampere-hour is really a unit of energy: the energy stored when a current of 1 ampere flows during one hour. To actually be an energy unit, a voltage must be assumed; this is usually 12 volt for a car battery.
Car batteries are normally rated in ampere-hour What does this mean?
simple. lets imagine you have a 70 Amp Hour battery (technically an accumulator, not a battery, but thats not important). the designation means it can sustain a 1 ampere continuous drain for 70 hours, or a 70 ampere drain for 1 hour. these figures are usually validated by certain temperature ranges etc,, hope this helps.
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.
MAh stands for?
mAh stands for milli Amp hour or milli Ampere hour. It refers to a measure of a battery's storage capacity.
