Genuine HP replacement battery

This genuine HP battery replaces part numbers M73466-005 and WP03XL in EliteBook 830, 835, 840, 845, 860 and 1040 models from the G9 and G10 generations. It uses lithium-ion chemistry at 11.58 V with a 4249 mAh capacity. The unit ships brand new in black.

Check your part number and generation

Confirm that your service tag lists M73466-005 or WP03XL before ordering. Verify the laptop is an EliteBook 830, 835, 840, 845, 860 or 1040 labelled G9 or G10. Ensure the existing battery is removable without specialised tools. Buyers needing a different voltage, capacity or form factor cannot use this unit.

Fits the existing battery bay

The pack slots directly into the original battery compartment and connects to the stock motherboard header. No additional cabling, adapters or firmware updates are required. It restores mobile runtime without occupying expansion ports or drive bays. Builders planning a multi-battery hot-swap setup should note this is a single internal module.
