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.
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).
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 .
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)
On the Internet I saw a NiMH battery 12V 50 Wh for about $50 USD so ten times that $500
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.
John Morganti gave this explanation of "Wh": The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt (1 W) ofpower expended for one hour (1 h) of time. The watt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications. The designation 5 Wh indicates that the battery will power a load of 1 watt for 5 hours or a load of 5 watts for 1 hour.
I don't understand the question. Batteries are rated at their watt-hour rating. This means the amount of energy the battery can delivery. However, these ratings are often exaggerated and in any event they are based on a specific use current -- other currents will change the actual watt-hours.
no wh is not a word
The time a good battery will last generally depends on the rate of discharge. There is a fairly handy way to find out if you have a bit more information. The DigiKey battery life calculator can easily be found on the web.
