Direct replacement for HP EliteBook G1/G2

This new lithium-ion battery is built for HP EliteBook 740, 745, 750, 755, 840, 845, 850 and 855 G1 and G2 models plus the ZBook 14 and 15u. It matches the original CM03XL form factor and connects to the same HSTNN-DB4Q, HSTNN-L11C-5, HSTNN-LB4R and 717376-001 part numbers. The pack delivers 11.1 V at 4000 mAh and is rated for up to 600 recharge cycles.

Upgrade from worn or swollen original cells

When an original battery no longer holds a useful charge or shows physical swelling, this unit restores full mobile runtime without changing the chassis fit. The 10.8 V compatibility marking means it slots into the same voltage rail as the factory pack. The jump is worth it whenever the notebook otherwise meets your workload but is tethered to an outlet.

Suits owners of the listed EliteBook

Buyers with an EliteBook G1 or G2 or a ZBook 14 or 15u can install this battery directly. Users of later EliteBook generations, other HP series or non-HP notebooks should look elsewhere because the connector and case keying differ.
