ok, I know that 4 1.25V batteries is equal to 500-Mi/H(or 5 volts), but how many milliamps per hour is just one 1.25V battery?

can you please tell me hoe you got your answer.

I assume what you want to know is the capacity of the battery in question. The capacity of a battery is measured in mA hours (mAh) not in mA per hour; in other words how much current the battery can supply for 1 hour before the battery drops below its useful operating voltage (eg. if you draw 1/2 this current the battery lasts 2 hours, 1/4 this current and the battery lasts for 4 hours, etc.). Most battery manufacters choose to not publish this number for Alkaline batteries as the mA hour rating varies depending on how quickly the battery is discharged. Some Re-chargeable AA NiMH (Nickle metal hydride) batteries can have capacities from 1100 mA hour to 2500 mA hour, but only provide 1.2 volts instead of the 1.5 volts of an AA Alkaline battery. Some of the re-chargeable batteries advertise 3 to 4 times the capacity of an Alkaline battery.

It depends on what kind of battery it is; alkaline, lithium, cadmium etc. and if it's a AAA or a D cell. You could probably go to something like the Eveready battery site and get the details for the one you're interested in.

That would depend on it's type of construction, Ni/Mh,Ni/Cd? ;-)=
