1 Wh = 1 Watt * 1 hour = 1 J/s * 3600 s = 3600 J. That''s the energy stored in the battery, which is completely not related to time. The larger the number, the more energy it supplies. 1Wh means if a device''s power is 1W, it can last for 1 hour with that energy. However usage time depends on the power consumption, not energy.

In a nutshell, watt-hours measure amounts of energy for a specific period of time, and watts measure rates of power at a moment in time. A common analogy for watts and watt-hours is speed and distance. Speed is a rate of how fast you drive at an instant in time (watts); distance is the length, or amount that you drive over a period of time ...
