Compatible HP ProBook models

The KingSener CI03XL replacement battery fits HP ProBook 640, 645, 650 and 655 series laptops from both G2 and G3 generations. It replaces a long list of original part numbers including HSTNN-UB6Q, HSTNN-PB6K and multiple 801517 variants. The black lithium-ion pack is brand new and rated at 48Wh with a nominal voltage of 10.95V.

Thermals and power in use

The 48Wh lithium-ion cell delivers stable 10.95V output during typical office workloads without excessive heat buildup. Normal operation keeps the battery temperature within safe limits for the supported ProBook chassis. Power draw follows the laptop's own management firmware, so runtime scales with screen brightness, CPU load and connected peripherals.

What the package changes

Installing this 100% new battery restores full mobile runtime to a ProBook whose original pack no longer holds charge. It enables continued untethered work on G2 and G3 models without requiring a mains connection. The direct part-number match means no BIOS updates or hardware modifications are needed for the swap.

Questions about this item

How do I install the KingSener CI03XL battery in my HP ProBook 640 G2?

Power off the laptop, disconnect the AC adapter, remove the base screws, detach the old battery connector, fit the CI03XL in the same orientation, reconnect the cable, replace the cover and screws, then charge fully before first use.

What maintenance will the CI03XL battery need over time?

Lithium-ion cells degrade with each charge cycle; store at around 50 % charge if unused for weeks, avoid constant 100 % charge while docked, and replace the pack when runtime drops below your needs.

What limit appears first during sustained heavy load on the CI03XL?

The 48 Wh capacity and 10.95 V output set the energy ceiling; under continuous high drain the voltage will sag and the pack will hit its low-voltage cutoff sooner than under light use.
