5-pound, 150 watt-hour
conformal battery was born out of the necessity to keep radios networked without weighing soldiers down with perhaps a dozen disposable batteries per day.
Energy generation jumped from 400 to 800 watt-hours
But to measure much smaller electricity use, such as a light bulb or hair dryer, it's more practical to use the unit watt-hour
The rover collected 161 watt-hours
of energy on the Martian day ending November 13.
The 320 watt-hours
the system will produce daily means that on a
Definitions: A megawatt-hour (MWh) is one million watt-hours
of electric energy or one megawatt of power used for one hour.
If you have a 200 amp-hour 12 volt battery, you will get 20 amp-hours at 120 volts (AC, DC, doesn't matter) because watts (rate of flow) and watt-hours
stay the same.
This battery stores 220 watt-hours
per kilogram and discharges up to 17 hours," says Licht.
