This NShi WP03XL lithium-polymer battery replaces part numbers WP03XL, HSTNN-OB2J, M64304-AC1 and M73466-005. It delivers 11.58V and 51.3Wh (4249mAh) in a black plug-and-play pack. The package includes the battery, a user manual and a tool kit for installation. Buyers with other EliteBook generations or non-HP laptops should verify compatibility before ordering.

Low heat and silent operation in daily use

Lithium-polymer chemistry runs cool during typical office workloads and produces no audible noise because there are no moving parts. Power draw follows the laptop's own management; the cell simply supplies the requested current up to its 51.3Wh capacity. No extra cooling or acoustic consideration is required beyond normal notebook ventilation.

Snap-in connector and included tools simplify

The battery uses the original keyed interface shown in the supplier images, so it seats with a firm click and no soldering. A small tool kit is supplied to remove the bottom case screws on the 830 G9 and 840 G9 chassis. Users who cannot open their device or who need a different connector layout will not be able to install this unit.

Questions about this item

How do I install the WP03XL battery in my EliteBook 830 G9, and what step is often missed?

Open the back case, disconnect the old battery, connect the new WP03XL using the included tool kit, then discharge to 5% and charge to 95% for 3-4 cycles to calibrate.

What replacement or maintenance will the 51.3Wh lithium-polymer pack need later?

After many charge cycles the 4249mAh capacity will degrade; replace with another WP03XL or compatible part M73466-005 when runtime becomes too short.

What limit appears first during sustained use of the 11.58V battery?

Continuous operation while the AC adapter is connected may damage the pack, so unplug the charger once the battery reaches full charge.
