Replacement battery for HP EliteBook G9 series
The Beisite WP03XL is a new lithium-ion battery rated at 11.58V with a capacity of 38Wh and 51.3Wh. It replaces part numbers WP03XL, M64305-421, HSTNN-LB8W, 31CP6/49/75 and WP03XL, M64304-AC1, HSTNN-OB2J, 31CP6/60/75. The black pack is built for Split X2 13-M000 and EliteBook 830, 840, 845, 860, 865 and 1040 G9 models.
Installing the pack restores mobile power
The battery fits directly into the compatible notebook chassis without extra cables or adapters. It frees the user from staying tethered to an AC outlet and supports the standard charging circuit of the listed EliteBook and Split X2 systems. No additional hardware is required beyond the laptop itself.
Suitable for owners of the listed HP models
Buyers with a Split X2 13-M000 or EliteBook 830, 840, 845, 860, 865 or 1040 G9 can use this unit as a direct swap. It is not for laptops outside that model list, for users who need a different voltage or form factor, or for anyone seeking a higher-capacity pack than the 38Wh and 51.3Wh rating.

Questions about this item
How long will the 51.3Wh capacity last before the 11.58V output drops under constant load?
The 51.3Wh rating shows total stored energy; run-time depends on the laptop's power draw and is not fixed by the battery alone.
Does the lithium-ion cell run hot or make noise during all-day use?
Lithium-ion batteries are silent and produce only normal warmth; no fan or moving parts are present.
Which HP part numbers must my laptop already use for this WP03XL to fit?
It replaces WP03XL, M64305-421, HSTNN-LB8W, 31CP6/49/75 and WP03XL, M64304-AC1, HSTNN-OB2J, 31CP6/60/75.
