These are two common ways battery capacity is measured.
Wh stands for "Watt hours", and it's a measure of the actual energy content of the battery; it measures how much power (watts) the battery can supply multiplied by the number of hours it can do so before it runs out.
Most batteries are labeled with a capacity in mAh (milliampere hours). This is a measure of the electric current the battery can supply multiplied by the number of hours it can do so. Example: if a battery is labeled 3000 mAh, it should be able to supply 3000 mA of current for one hour, 1500 mA of current for 2 hours, etc. You can figure out the Watt hours for a battery by multiplying the voltage of the battery by the amp hours (amp hours = millamp hours / 1000).
Only if the battery is rated at 11.66V. mAh / 1000 => Ah (4800 mAh = 4.8 Ah) Ah * V => Wh (4.8 Ah * 11.66 V = 55.97 Wh)
Answer #1:56watt = 56000mw,1000milliamp = 1amp,watt = amp x volt = watt/volt,if the battery is rated 11.1v,so 56000mw/11.1v = 5 045.04505mah==============================Answer #2:Answer #1 has a big ' if ' hidden in it.In general, 56 Wh = 56,000/voltage of the battery mAh and for ANY number of Wh ... call it ' P ' ...P Wh = 1,000 P/battery voltage mAh .
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.
The difference is an increased battery capacity (hence longer runtime). A batteries capacity is measured in Ah (or mAh) and is the product (ie multiplied together) of the current being drawn and the time the current is drawn for. Thus a 4800 mAh battery can supply a 2A current for 2.4 hours (ie 4800/2000) while a 4400 mAh battery can only supply a 2A current for 2.2 hours.
It depends on the voltage. WH = Watt Henry, mAH = milliamp Henry, watts = amps * volts and milliamps= 1000 * amps. Thus the conversion is: mAH = 1000 * WH / V, where V is the voltage. I'm looking at the battery for my Dell Studio and it's rated 85WH and 11.1V. So it's 1000 * 85 / 11.1 = 7658 mAH, so in this case 85WH is better than 6600 maH. If we solve 1000 * 85 / V = 6600, we get V = 12.9. When converting from WH, the bigger the voltage the lower the mAH. So for voltages bigger than 12.9 V, 6600mAH is better than 85WH. Hope this helps.
4400mah
the 56 wh has a higher capacity and will last about 30 mins longer.
Wh means Watt-Hour. It indicates how long your battery will last. The higher the Wh, the longer your battery will last.
The letters Wh means watt hours. this is how many hours of power the battery can store. The larger the number, the more power the battery can store. This is important for laptops, smartphones, and tablets. or Another way to measure the capacity of the battery is in watt-hours(wh). wh is calculated by multiplying the number of Amps with the battery voltage.
watt = amp * volt watt hour capacity = amp hour capacity * voltage Calculate capacity in watt hour for the one which gives you mAh capacity with the following (dividing by 1000 to convert mA to A): Wh capacity = (mAh capacity / 1000 ) * voltage - Neeraj Sharma
