Higher mAh on rechargeable batteries = more power or longer life?
If i buy 1000mAh batteries over 750mAh what will happen if i put it in a LED flashlight: will it be brighter or last for longer?
and if it is brighter: how would it change the performance in my mp3 player which probably uses a constant amount of energy regardless of how many mAh there are..
Also if you know, what exactly is mAh?
mAh = milli ampere hour. 1/1000 ampere for 1 hour. Ampere is the measure for current in a device. Voltage is the measurement for power in a device. Example: A water hose with (Volts) 40 lbs. pressure will shoot a stream much farther than one with 20 lbs. pressure. A (Ampere) one inch water hose will supply much more the water than would a 1/2 inch water hose at the same (volts)pressure. A higher mAh battery of same voltage simply runs a device longer.
