Compatible HP ProBook G8 replacement

This new lithium-ion battery replaces part numbers RH03XL, HSTNN-DB0B and related HP codes across ProBook 430, 440, 450, 640 and 650 G8 models. It delivers 45Wh at 11.4V in a black housing and carries a 12-month warranty. The cell chemistry matches the original specification for direct swap-in.

Upgrade from depleted or failing original

When the factory pack no longer holds charge or shows swelling, this unit restores full runtime without BIOS conflicts. The jump is worth it if your current battery reports reduced capacity, unexpected shutdowns or a service alert. It covers all listed G8 sub-models including 203F4EA, 2M2U3ES and 2Q525AV.

Verify exact model and part number first

Check the sticker on your existing battery for RH03XL, HSTNN-UB7X, HSTNN-IB9P or any listed M01524 or M02027 code before ordering. Confirm the laptop chassis is a ProBook G8 — earlier G7 or later G9 units are not supported. Ensure the voltage reads 11.4V on the original label.
