MAh ? Battery

Asked Jul 26, 2008, 07:42 PM — 4 Answers
What does mAh stand for and how do you determine how many mAh's your cell battery should have. This is not listed in my manual.
I have L1400 with a 3.7V 750mAh.

Thanks

The "Ah" in mAh stands for ampere-hour, or the charge provided by a current of 1 ampere for the duration of 1 hour. The "m" stands for milli, or one-thousandth, so mAh stands for millampere-hour. 1 Ah = 1000 mAh. The greater the mAh, the greater the battery capacity and typically the longer the battery will power a device. The tradeoff for longer runtime is usually increased weight, cost, or physical bulk and the choice is yours.

However, a battery rated at 1000 mAH may not deliver 1 A for 1 hour. The rate isn't linear. It's just a way of determining capacity or how much energy is in the battery.

The other thing is that because every phone is different you can't count on a 1,000 mAH for 1 phone that last 7 hours of talk time may only last for 4 hours on a different phone.
