Questions about this item

How long will the 56Wh 3-cell pack last under continuous load before it needs recharging?

The 56Wh capacity delivers runtime proportional to your laptop's power draw; a typical 15 W workload yields roughly three to four hours on a full charge.

Does the lithium-ion pack run hot or make noise during all-day operation?

The battery is a passive component with no fan; it warms slightly under heavy discharge but stays within normal operating temperatures for lithium-ion cells.

Which HP part numbers must match the original battery for this CC03XL replacement to fit and connect?

Confirm your existing battery shows CC03XL, HSTNN-DB9O, HSTNN-UB8W, L77622-2C1, L77622-2C2, L77622-541 or L77991-005 and that the connector position matches the product photo.
