hi,
need some clarification.
if a battery storage capacity is 9v 2100mah,what does 2100mahh stand for???
-
is the second one supposed to have 2 h's?
-
NO!
and that means that thiss battery can give 2100mA for an hour. if u use less amps then it will last longer. say you need 1050 amps, then the battery will last for 2 hours etc :)

1050 ma not amps! that is some high current stuff
mah stands for milliamps hour , as robonoob said it can give 2100 milliamps continuously for a hour

oops :D yea thats what i ment. mAmps not Amps :)

Thats nothin'. I once bit into a 4 trillion amp wire just to see what would happen.... (holy crap imagine the wire thickness needed to contain that much amperage... it would have to have the same diameter as friggen Jupiter lol)
"mAh" = "Milliamp hours"
To find out how long said battery will last, there is a simple equation:
[battery-mAh-rating] / [circuit-mA-requirement] = [battery-life-in-hours]

:) It simply means that if u takes 2100ma current from urs battery then it can run for 1 hour
