PISKEKAT 6-cell Li-ion battery for HP ProBook

The PISKEKAT CA06XL is a new 6-cell lithium-ion laptop battery rated at 5200 mAh and 11.1 V. It replaces a long list of HP part numbers including 718677-421, 718678-421, HSTNN-DB4Y and HSTNN-LB4Y. The pack is built with overcharge, overdischarge, over-temperature and short-circuit protection and is rated for up to 500 recharge cycles. It fits HP ProBook 640, 645, 650 and 655 models in both G0 and G1 generations.

Who this suits and who should look elsewhere

This battery suits owners of the listed ProBook models who need a direct replacement for an original CA06 or CA06XL pack. Buyers whose laptop uses a different part number or a higher-capacity 9-cell design should look elsewhere. The product is a single battery only; no AC adapter, tools or mounting hardware are included.

5200 mAh capacity decides fit

The 5200 mAh capacity is the single specification that determines whether this pack matches the runtime of the original battery. If the original part was rated at a different milliampere-hour value, the replacement will change the usable runtime accordingly. Verify the mAh figure on the old battery before ordering.
