To convert from energy to electrical charge, use the formula below in conjunction with the voltage. Q (mAh) = E (Wh) × 1,000 V (V) Thus, the charge in milliamp-hours is equal to the watt-hours times 1,000, then divided by the voltage. You can also convert mAh to Wh using a similar formula. For example, let''s convert 10 Wh at 12 V to mAh. So ...
Since batteries are storage units for electrical energy, watt-hour specifications equal battery capacity. For Energizer batteries, the manufacturer chooses milliamp hours rather than watt-hours. To convert milliamps to watts, it becomes necessary to convert milliamps to amps (1,000 milliamps in one amp), and then use the …
Lead-acid (LA) batteries. LA batteries are the most popular and oldest electrochemical energy storage device (invented in 1859). It is made up of two electrodes (a metallic sponge lead anode and a lead dioxide as a cathode, as shown in Fig. 34) immersed in an electrolyte made up of 37% sulphuric acid and 63% water.

Multiply the power consumption in watts by the duration of use in hours. Using our example, for a 60-watt light bulb used for 3 hours, the calculation would be: 60 watts x 3 hours = 180 watt-hours. 4. Interpret the Result: Results: 180 watt-hours, represents the total energy consumption over the specified period.
A watt-hour (Wh) is a unit of energy; it''s 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. Power companies typically charge you for electrical energy by the kilowatt-hour (kWh), which is equal to 1,000 watt-hours.
5 · Gigawatt hour, abbreviated as GWh, is a unit of energy that represents one billion (1 000 000 000) watt-hours and is equal to one million kilowatt-hours. Gigawatt hours are mostly used as a measurement of the output of large electric power stations. One gigawatt could power 10 million watt bulbs. With a much lower energy consumption, one ...
