Replacement battery for HP ProBook G8

This 3-cell lithium-ion unit replaces the original RH03XL pack in ProBook 430 G8, 440 G8, 445 G8, 450 G8, 455 G8, 630 G8, 640 G8 and 650 G8 models. It delivers 11.4 V and 45 Wh from a 3947 mAh cell stack. The black casing matches the factory aesthetic and the pack is certified to CE, FCC and RoHS standards.

Fits the existing battery bay without modification

The pack slots into the same compartment used by the OEM battery, requiring no adapter or cable change. It restores mobile operation for users whose original cell has degraded, freeing the notebook from permanent mains connection. Buyers needing a higher-capacity 4-cell or 6-cell option will not find it here.

Steady output during extended sessions

The 3-cell chemistry maintains the rated 11.4 V through long work periods without the voltage sag seen in worn packs. Low self-discharge keeps charge viable during storage. Thermal protection circuits prevent overheating under sustained load, though the 45 Wh capacity still limits unplugged runtime compared with larger packs.

Questions about this item

How long will the 3-cell 45 Wh battery last under continuous heavy load?

The 3947 mAh pack at 11.4 V stores 45 Wh; run time depends on the laptop's power draw, so a 450 G8 under full load will drain it faster than a 430 G8 at idle.

Does the battery run hot or make noise during all-day use?

Lithium-ion cells produce no noise; warmth is normal during charge or high discharge, but the pack includes circuit protection to keep temperatures within safe limits.

Which HP ProBook models accept this RH03XL part without extra hardware?

It fits ProBook 430, 440, 445, 450, 455, 630, 640 and 650 G8 models directly; no additional cables or adapters are required.
