Replacement Battery for HP ProBook Series

This 11.4V 48Wh lithium-ion unit replaces part numbers CI03 CI03XL HSTNN-UB6Q 801554-001. It fits HP ProBook 640 G2 645 G2 650 G2 655 G2 series notebooks. A-grade cells support up to 500 recharge cycles with fast charging and slow discharging. The black pack carries CE FCC and RoHs certification.

Thermals Noise and Power Draw

Lithium-ion chemistry runs cool during typical office workloads and produces no audible noise. The 48Wh capacity delivers steady voltage for everyday tasks without excessive heat buildup. Power draw matches original specifications for compatible ProBook models. Normal use stays within certified safety limits.

Sustained Load Behaviour

Under continuous demand the pack maintains stable output thanks to A-grade cell construction. Discharge remains gradual across the full cycle count rather than dropping sharply after a few months. The design supports consistent runtime during long work sessions away from mains power. Certification covers extended operation at rated voltage.

Questions about this item

How do I install the CI03XL battery in my ProBook 650 G2, and which step do people get wrong?

Power off the laptop, unplug the AC adapter, slide the release latch to unlock the old pack, lift it out, align the new CI03XL contacts, press firmly until the latch clicks, then reconnect power. The step most often missed is pressing evenly on both ends until the latch audibly engages.

What maintenance will the 48Wh lithium-ion pack need and when must it be replaced?

No routine maintenance is required; avoid full discharges and store at roughly half charge if unused for weeks. The pack is rated for up to 500 recharge cycles, after which capacity loss typically warrants replacement.

What limit appears first during sustained heavy load on this 11.4V battery?

The 48Wh capacity is the first limit; under continuous high drain the charge depletes quickly and voltage sag can trigger the laptop's low-power throttling before thermal limits are reached.
