Buyers needing a different voltage or capacity should look elsewhere.

Thermals and power in daily use

The cell chemistry delivers steady 11.4V output during typical office tasks and web browsing without generating noticeable heat inside the chassis. Power draw follows the laptop’s own management profile so the battery does not impose extra thermal load on the cooling system. No active cooling components are present on the pack itself.

Behaviour under sustained load

During extended workloads such as video playback or light rendering the pack maintains its rated 42Wh capacity until the system initiates its low-power state. Voltage remains stable at 11.4V throughout the discharge curve. The battery is not designed for high-current applications beyond the original laptop specifications.
