Meanings of watt-hour in English

Through the 1890s, various iterations of the induction watt-hour meter were becoming standard technology.

The battery is the same 77.5 watt-hour model as before, and the case is virtually identical.

Thomson invented a commutator watt-hour meter (that measured the energy consumed), also in 1888, and brought it to market the following year.

The wings and fuselage are covered with 17,000 photovoltaic panels that charge the 260 watt-hour per kilogram pack of lithium-ion cells powering four 17.4-horsepower motors.

The average working requirement for heavy vehicles is about 50 watt-hours per 1000 lb.

The iPad actually has two batteries wired in parallel, for a total of 24.8 Watt-hours.

They hold almost the exact same charge, though: 25 Watt-hours vs. 24.8 Watt-hours of the original.

It lists the Macbook Pro battery with an energy of 77.5 Watt-hours (or 2.79 x 105 Joules).

Encased in plastic, ReadySet is about the size of a shoe box, and it stores 54 watt-hours of power in its field-ready battery pack.

Seeo's advanced lithium polymer cells have an energy density of 350 watt-hours per kilogram, roughly twice the level of batteries used in today's electric vehicles.

Apple's 10-hour promise seems right on target, if not at the low end of what its 23.8 Watt-hour battery can deliver.

A typical lithium-ion battery can store 150 watt-hours of electricity in 1 kilogram of battery, representing more than double the capacity of nickel batteries.

The specific output can be made as high as 10 or 11 watt-hours per pound of cell, but this involves a chance of shorter life.
