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.
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)
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.
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.
There should be no problem in a cell phone, it will take a little longer to charge but it will also give you 33% more operating time before you need to recharge the phone.

To calculate the number of hours a 4400 mAh battery will last, you need to know the current draw of the device it powers. If you have the current draw in milliamps (mA), you can divide the battery capacity (mAh) by the current draw to get the number of hours. For example, if the device draws 200 mA, the battery will last approximately 22 hours (4400 mAh / 200 mA = 22 hours).
No reason why not. So long as the physical size of the battery matches, and the voltage it delivers is the same - you should be able to replace it with the higher mAh battery.
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.
A Radio Wave within the RF spectrum range of 4200 - 4400 MHz
To compare 21.6 watt-hours (Wh) to 4400 milliamp-hours (mAh), you need to know the voltage of the battery. Watt-hours is a measure of energy, while milliamp-hours is a measure of electric charge. If you assume a common lithium-ion battery voltage of 3.7 volts, you can convert 4400 mAh to watt-hours using the formula: Wh = (mAh × V) / 1000. This would yield approximately 16.28 Wh, which means 21.6 Wh is greater than 4400 mAh at 3.7 V.
can use 1400mah battery to replace 760 mah
Sure, if they have the same voltage.
