Direct Replacement Battery
This Dr. Battery Professional Series unit replaces original HP batteries across EliteBook 735, 745, 830, 840, 846 and ZBook 14u models from the G3 to G6 families. It matches the 11.55V voltage and 4330 mAh capacity of the factory packs using OEM-grade Li-polymer cells.
Upgrade From Degraded Packs
The jump is worth it when an existing battery no longer holds a full charge, shows swelling, or triggers safety warnings about over-heating or short-circuit risk. Built-in protection circuits guard against over-charging and over-discharging to extend cycle life beyond what worn cells can deliver.
Sustained Mobile Workloads
Under continuous office and travel use the Li-polymer chemistry maintains stable voltage without the sharp drops seen in aged packs. The 50Wh energy rating supports long meetings and flights, while the 8.0x1.5x0.8 cm form factor fits the original bay without modification.

Questions about this item
Will the 8.0 x 1.5 x 0.8 cm battery fit my EliteBook 840 G5 without a chassis modification?
The pack measures 8.0 x 1.5 x 0.8 cm and matches the original SS03XL form factor used in EliteBook 840 G5 and G6 models, so it seats in the existing bay without any cutting or shimming.
What is the most common mistake when installing this 11.55 V Li-polymer battery?
Many installers forget to disconnect the internal cable before removing the old pack; always unplug the old battery from the motherboard first, then connect the new 4330 mAh unit before refitting the bottom cover screws.
When should I plan to replace the 4330 mAh cell in my ZBook 14u G5?
Replace the battery when runtime falls well below your normal workload or the OS reports a permanent capacity loss; the built-in protection circuit guards against over-charge, over-discharge, over-heat and short-circuit during its service life.
