Direct replacement for HP business laptops

This 3-cell lithium-ion battery replaces part number CC03XL and matches the 11.55 V, 53 Wh specification used in HP ZBook Firefly 14 G7 and G8 as well as EliteBook 830, 835, 840 and 845 G7 and G8 models. It fits the original connector and cable layout without modification.

Steady capacity through a full workday

The 4400 mAh pack delivers consistent voltage under continuous office workloads such as document editing, video calls and browser sessions. Lithium-ion chemistry avoids memory effect, so partial charges do not reduce usable capacity over time.

Low heat and silent operation

The cell pack runs cool during typical business use and adds no audible noise to the system. Certified to CE, FCC, UL and RoHS standards, it meets safety requirements without increasing the laptop’s thermal load or power draw.

Questions about this item

How much heat does the 3-cell 53Wh lithium-ion battery generate during all-day use?

The 3-cell 53Wh lithium-ion pack runs at 11.55V and 4400mAh; normal operation stays cool because the chemistry is low-maintenance with no memory effect, and the supplier notes high temperature resistance from OEM-grade compounds.

What must I already own to install the CC03XL replacement battery?

You need a compatible HP laptop — ZBook Firefly 14 G7 or G8, EliteBook 830, 835, 840 or 845 G7/G8 — plus a screwdriver to open the back cover and verify the connector position and cable length match the original CC03XL, HSTNN-DB9Q, HSTNN-IB9F or HSTNN-LB8Q unit.

Will the 11.55V 53Wh battery work alongside the original charger and power management on my EliteBook 840 G8?

Yes — the pack replaces part numbers L77608-271, L77608-421, L77608-1C1, L77608-2C1 and L78555-005, so it uses the same 11.55V interface and works with the laptop’s existing charging circuit and firmware without extra setup.
