The battery can supply an amount of electric charge measured in milliampere-hours, which expresses its capacity to supply a load of a number of milliamps for a number of hours. The idea is that if the load current is high, the battery lasts for less time, so the current times the time makes good measure of the capacity.
It is also common practice to measure larger batteries in amp-hours, and there are 1000 mAH in one AH. This measure is a nominal one because in practice a high current load will give a lower AH capacity than when the load is small.
Multiplying the voltage by the AH capacity gives the watt-hour capacity, which measures how much energy the battery can supply. This measures is also only a nominal only because as the battery runs down its voltage reduces.

What is mAh?
mAh = milliamp hours, which is battery capacity
What is the difference between 800 mAH and 700 mAH?
These figures represent capacities of use for batteries. If a device uses 50 mA an hour on a 800 mAH battery, the device would operate for 16 hours before depleting the battery. If the same device was connected to a 700 mAH battery, the device would operate for 14 hours before depleting the battery.
How many mAh is a D size battery?
That would depend on the actual battery's specifications. I've seen some D cells rated as low as ~2000 mAh. However a full true D cell should have a rating between 10,000 mAh and 15,000 mAh.
What is 6600 mah mean?
Do you mean 6600mAh? In relation to a battery this would mean a capacity of 6600 milli-Ampere hours. In other words the battery can supply 6600mA for 1 hour.
Will 1000 mah charger damage 500 mah battery?
probably, yes. imagine putting twice a much AA's in your radio or whatever.
Is 4800mAh is equivalent to 56 Wh?
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)
How does 21.6 Wh compare to 4400mAh?
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.
How much is 56Wh in MAH?
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 .
How much electrical energy is supplied by the battery?
The amount of electrical energy supplied by the battery is measured in units called watt-hours (Wh). This value can vary depending on the capacity of the battery, which is typically listed in milliampere-hours (mAh) or watt-hours (Wh).
How does 47 Wh compare to 4400 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.
What does 56Wh mean on dell lap top battery?
Wh means Watt-Hour. It indicates how long your battery will last. The higher the Wh, the longer your battery will last.
Which is better the 6600 mah or 4400 mah li-ion battery for a laptop?
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.
How does 44 wh compare to 44 mah?
4400mah
What does 85 Wh mean?
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.
What is better 4400Mah of 73Wh?
To compare 4400mAh and 73Wh, we need to know the voltage of the battery, as capacity (mAh) and energy (Wh) are related by the formula: Wh = (mAh × Voltage) / 1000. Without the voltage, we can't directly compare them, but 73Wh indicates a higher total energy capacity if the voltage is similar. In general, higher Wh is better for longer usage times, assuming other factors like weight and size are acceptable.
What is the difference between Wh and Mah on a battery?
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).
How do you know when your airsoft battery is done charging?
You simply divide the MAH of your battery the MAH of your charger. For example my battery is 1500 MAH and my charger is 250 MAH. 1500/250=6 which means I have to charge my battery for six hours.
