51.3 Wh Li-ion replacement battery
This 51.3 Wh lithium-ion battery operates at 11.58 V and is built as a direct replacement for the original pack in compatible HP EliteBook and ZBook 2-in-1 models. It uses grade A cells and carries CE and UL safety certifications. The unit is supplied new and ready to install.
Capacity and runtime headroom
At 51.3 Wh the pack delivers the same nominal energy as the factory battery, supporting typical office workloads and light mobile use for a full workday. Heavy multi-tasking, sustained high brightness or continuous video playback will reduce available runtime proportionally. The battery is not intended for extended off-grid sessions without recharging.
Thermals, noise and power draw
The battery itself generates no audible noise and adds no active cooling requirement. Under normal charge and discharge cycles it operates within the thermal envelope defined by the host laptop’s power management. No additional power draw beyond the laptop’s standard charging circuit is introduced.

Questions about this item
Will this 51.3Wh 11.58V Li-ion battery fit alongside the original charging circuit in my HP EliteBook 840 G10?
Yes, it replaces part numbers WP03XL, M73466-005 and others listed for the EliteBook 830, 835, 840, 845, 860 and 865 G9 and G10 series, so the existing charging circuit will recognise it normally.
How can I verify the battery is working correctly after I install it?
The laptop should power on, show the correct 51.3Wh capacity in the BIOS or OS battery report, and charge to full without error messages.
What comes in the box and do I need any extra parts to fit it?
The package contains the replacement battery only; no tools, screws or cables are included, so reuse the fixings from your old battery or source them separately.
