#### Is 4400 mAh the same as Mah?

The answer is yes, mAh only refers to power capacity and how many milliamps the laptop battery can deliver per hour. The more important compatibility measurement is the voltage it supplies. Most laptop battery makers advertise their batteries power capacity in terms of 4400, 5200, 5600 or 5800 mAh.

How many watts is a 5200 mAh battery?

Answer: millamps (mAh) x voltage (V) = watt hours (WH) Example 1: 4400 mAh x 11.1 V = 48.8 WH also 4400 mAh @ 10.8 = 47.5 WH. Example 2: 5200 mAh x 11.1 V = 57.7 WH also 5200 mAh @ 10.8 = 56.1 WH. The take away here is that not all 6 cell or 9 cell laptop batteries will power you laptop for the same amount of time.

What does Mah mean on a battery?

etc… The mAH specification shows how long a battery will be able to last in a circuit, given the circuit’s power requirements, how much current the circuit demands. Being that the mAH is the battery’s life in terms of current capacity, the more mAH’s means the longer a battery can last, or the more current it can supply in a circuit.
