  • Up to 48 Wh capacity powers HP ProBook 640 G2, 645 G2, 650 G2, 655 G2 and 645 G3 models
  • 4 V lithium-ion chemistry with Grade A NMC cells delivers stable current and long run-time
  • Built-in smart chip provides over-charge, over-discharge, over-current, over-voltage and short-circuit protection

  • Rated for about 500 recharge cycles with no memory effect and low maintenance

Replacement battery for HP ProBook G2 and G3

This lithium-ion unit replaces the original CI03 and CI03XL packs used in HP ProBook 640 G2, 645 G2, 650 G2, 655 G2 and 645 G3 laptops. It delivers the same 11.4 V output and fits the existing battery bay without modification. Buyers needing a different voltage or form factor should look elsewhere.

Capacity rated at 46 Wh or 48 Wh

The pack supplies either 46 Wh or 48 Wh depending on the specific cell configuration shipped. That energy reserve powers typical office workloads for several hours before requiring a recharge. Runtime will fall short for users running sustained heavy compute or discrete graphics loads.

Grade A cells with multi-protection circuitry

Grade A NMC cells are paired with a third-generation smart chip that provides overcharge, over-discharge, overcurrent, overvoltage, short-circuit and thermal safeguards. The battery is rated for roughly 500 recharge cycles and carries CE, FCC, RoHS and UL safety certifications. No periodic calibration is required.

Questions about this item

Will the 11.4 V 46 Wh or 48 Wh pack fit my ProBook 640 G2 that still uses the original HSTNN-UB6Q?

Yes — the replacement matches the 11.4 V 46 Wh or 48 Wh rating and lists HSTNN-UB6Q among its compatible part numbers, so it slots straight into the 640 G2, 645 G2, 650 G2 or 655 G2 chassis.

How can I confirm the smart chip is communicating correctly after I install the battery?

Open the HP BIOS or the Windows Battery Report; both will show the new 11.4 V pack, its design capacity of 46 Wh or 48 Wh, and a healthy cycle count starting near zero.

Does the package include a charger or just the battery itself?

Only the battery is supplied — the CI03 / CI03XL unit with built-in protection circuits. You reuse your existing HP AC adapter.
