Replacement battery for HP Pro Tablet x2 612 G1

This lithium-ion cell is built to replace the original HSTNN-IB6E pack in the Pro x2 612 G1 tablet. It arrives new and ready to install for owners whose factory battery no longer holds a useful charge.

29 Wh capacity at 7.4 V

The 29 Wh rating restores the tablet’s original runtime for typical office tasks and media playback. Heavy workloads or high screen brightness will drain the pack faster, so users who need all-day autonomy away from power should plan for a recharge or a spare.

Direct fit for the Pro x2 612 G1 chassis

The battery matches the OEM form factor and connector, so it slots into the existing compartment without adapters or case modifications. No extra cables or mounting hardware are required, freeing up workspace and keeping the tablet’s profile unchanged.
