Sustained discharge at 11.4 volts

The cell chemistry delivers a nominal 11.4V across the discharge curve, so voltage remains stable during long work sessions rather than sagging after a short burst. Rated at 42Wh, the pack is designed to maintain usable capacity over repeated daily cycles. No additional thermal management or firmware calibration steps are described in the specifications.

Single-bay form factor limits expansion

The battery occupies the standard internal bay for the listed models, so only one pack can be installed at a time. Users needing more runtime must carry a spare or use an external power bank. The replacement part numbers cover the original equipment variants but do not add extra cells or higher-watt-hour options beyond the stated 42Wh.
