HP EliteBook and ZBook 14U Compatibility

This 11.55V lithium-ion battery fits HP EliteBook 730, 735, 740, 745, 830, 840 and 846 G5 models. It also supports EliteBook 735, 745, 830 and 840 G6 units plus ZBook 14U G5 and G6 workstations. The three-cell design matches the original form factor for a direct swap without modification.

50 Wh Capacity and Three-Cell Layout

The 50 Wh rating provides a practical energy reserve for typical office applications, web browsing and media playback on supported ultraportables. A three-cell pack keeps weight low while delivering enough headroom for a full workday under moderate load. Runtime shortens noticeably during sustained heavy compute tasks or maximum screen brightness.

11.55V Lithium-Ion Interface Limits

The fixed 11.55V output is calibrated for the EliteBook and ZBook 14U charging circuits listed above. Using this pack outside that model range risks voltage mismatch and potential damage to the laptop power subsystem. Lithium-ion chemistry also degrades with deep discharge cycles and prolonged storage at full charge, so periodic calibration helps maintain reported capacity accuracy.

Questions about this item

Will this 11.55V 50W 3-cell battery fit my EliteBook 840 G6 without changing the chassis?

Yes, the battery is listed as compatible with EliteBook 840 G6 and uses the same 11.55V 3-cell form factor, so it installs in the original bay without modification.

How can I confirm the battery is charging correctly after I install it?

After fitting the battery, power on the laptop and check the OS battery indicator; it should show charging at 11.55V and report a design capacity near 50 Wh, confirming the new pack is recognised.

Does the package include any tools or a replacement AC adapter?

The box contains only the 3-cell lithium-ion battery; no screwdrivers, cables or AC adapter are supplied, so reuse your existing charger and any case screws.
