Watt Hours:This is a far more accurate way to know how much usable energy is in a given battery pack (abbreviated Wh) when available, this is the number to look for! Also, you can translate it into how many watts, continuous, for 1 hour! A 500wh battery can deliver 500 watts for 1 hour or 1000w for 30 minutes. or 250w for 2 hours.. etc..

What does mAh & Wh stand for? mAhstands for milliamp hourand Whstands for Watt Hourand it is how a battery's energy storage capacity is measured. Watt Hour is now the more common way of measuring battery storage since it accounts for both capacity and the voltage and gives a more accurate measure of how long your battery will last.
What is the difference between a watt and a watt-hour A watt-hour (Wh) is a unit of energy; its a way to measure the amount of work performed or generated. Household appliances and other electrical devices perform work and that requires energy in the form of electricity. Utilities typically charge you for electrical energy by the kilowatt-hour (kWh), which is equal to 1,000 watt-hours.
What is watt-hour (Wh)? - Definition from WhatIsSep 21, 2005 · An energy expenditure of 1 Wh represents 3600 joule s (3.600 x 10 3 J). To obtain joules when watt-hours are known, multiply by 3.600 x 10 3. To obtain watt-hours when joules are known, multiply by 2.778 x 10 -4. In general, energy ( E) is equivalent to power ( P) multiplied by time ( t ).
If you have a specific question, we'll be more than MJ/kg (the batteries in a Tesla are about 0.7 MJ/kg), so they have a fraction of the storage of liquid fuels. The best battery technology in theoretical development (Lithium-air) has a theoretical maximum of 41 MJ/kg, more realistically they'll get 1/4 to 1/3 of that from the technology Convert Amp hour to Watt hour (Ah to Wh)Convert Amp hour to Watt hour (Ah to Wh) Insert the Amp hours (Ah) and voltage (V) below and click on Calculate to obtain Watt hours (Wh). Formula is (Ah)* (V) = (Wh). For example, if you have a 2 Ah battery rated at 5 V, the power is 2Ah * 5V = 10Wh.
