Thermals noise and power draw in normal use

The pack uses UL-certified cells designed for standard office workloads such as document editing, web browsing and video playback. At 11.4V nominal voltage it delivers steady current without excessive heat during typical daily cycles. The 47Wh capacity supports several hours of unplugged use depending on system configuration and screen brightness.

Behaviour under sustained load rather than short

Rated for 500 recharge cycles, the battery maintains capacity through repeated full discharges such as long meetings, travel days or field work. Continuous high-drain tasks like rendering or large compiles will deplete the 47Wh reserve faster than light use, but the cell chemistry is built for consistent output across the cycle life.
