This is an informal unit for energy, often used for batteries. mAh = milliampere x hours. If you know how much current you will need (in milliamperes), you can divide the 4400 mAh by the amount of current, to calculate how many hours the battery will last.
It depends on the voltage. Divide the watt-hours (Wh) by the voltage (V) and you will get the Ampere-hours (Ah). So if the voltage is at 10.8V, divide 47 Wh by 10.8V to get about 4.352 Ah. Finally, convert the Ah to milli-Ah (mAh) by multiplying by 1000 to get 4,352 mAh which is rounded to 4400 mAh. So 47 Wh at 10.8V is about 4400 mAh. -UnrivaledShogun.

10% = 44000/10 = 4400 1% = 4400/10 = 440 5% = 440x5 = 2200 or 5% = 4400/2 = 2200

4400
Yes it does! 1000 mAH = 1Ahr 1Ahr = 1000 mAhr 4.4 Ahr * 1000 = 4400 mAH 4400 mAh / 1000 = 4.4 Ahr mAH milli Amp Hours (1000 thousandth of Amp Hour)

There are 5 ampere hours in 5000 mAh
Yes, this is possible. The digits refer to the battery life as measures in milliamperehours (mAh). If "x" indicates the old battery and "y" indicates the new, then the equation (60/4200)*4400 will indicate how much longer the battery will last.
40 hours
It depends on the voltage being used. To get 4400 mAh (milliamperes per hour) converted to Wh (watt-hours), do the following: Divide the mAh by 1,000: 4,400mAh/1,000=4.4Ah (amperes per hour) Next, take the amount of amperes per hour and multiply that by the voltage being used (we'll just use 12 volts as an example): 4.4Ah*12V=52.8Wh I hope this helps!
It's not a question about "better", it's about what's most important to you - weight/size or runtime. The 4400 mAh battery will let you run the laptop on battery longer, but will probably also make it a little bit bigger/heavier. More to carry around. The 2550 mAh will last a bit shorter, but will keep the laptop smaller and lighter. You have to decide what's important to you.
mAh = milliamp hours, which is battery capacity
Depends on your speed. Divide 4400 by the average speed and you have your answer.
Yes, but only if the power supply design of the laptop allows it, because the charge controls are dependent on the battery. Ask the manufacturer first.
A battery rating of 4400 mAh means that the battery can nominally produce 550 mA for 8 hours. Even though it would seem that the battery will produce 4400 mA for 1 hour, it will not actually last that long. By convention, current-time ratings on batteries are normalized to an 8 hour rating.
mAh is a rating of a battery's capacity. A 4400 mAh battery is capable of delivering 4.4 amps of current for one hour. A 6600 mAh battery is capable of delivering 6.6 amps for one hour. That is not to say that both batteries will only last for one hour, since the laptop will probably draw less current than that. The important thing to notice is that the 6600 mAh battery has 50% more capacity than the 4400 mAh battery. If battery life is your #1 priority, the larger battery would be a good choice. However, it may be larger and heavier than the 4400 mAh battery. If a small, lightweight laptop is #1 priority, the smaller battery might be better. Also, if the laptop will not be unplugged, on the go all the time, the smaller battery might be a better choice due to it being cheaper. As all things engineering, there are compromises to be made.
