53Wh Li-polymer replacement battery

This 53Wh lithium-polymer pack operates at 11.55V and delivers 4400mAh capacity. It replaces part numbers CC03XL, HSTNN-IB9F, L78555-005 and L77608-1C2. The unit is built for HP EliteBook 830, 835, 840 and 845 models across G7 and G8 generations. It suits professionals who need a direct-fit power source for daily mobile work.

Sustained discharge behaviour

The cell chemistry maintains a steady voltage curve through typical office workloads rather than spiking under short bursts. Capacity remains stable across repeated charge cycles when the laptop thermal management keeps the pack within normal operating temperatures. Users running continuous video calls or compilation tasks will see consistent runtime without sudden drops. Builders who need hot-swap capability or a second battery for extended off-grid sessions cannot use this single-pack design.

Connector and form-factor limits

The battery mates only with the proprietary CC03XL interface found on the listed EliteBook and ZBook Firefly 14 chassis. No adapter cable or alternative connector is included, so it cannot serve laptops outside the specified model range. Physical dimensions match the original bay exactly, preventing use in thinner ultraportables or thicker workstation frames.

Questions about this item

Does the 11.55V 53Wh Li-polymer pack run hotter than the original during all-day use?

The replacement matches the factory 11.55V and 53Wh rating, so thermal behaviour stays the same as the original CC03XL unit.

My EliteBook 840 G8 charges via USB-C — will this 4400mAh battery work without the barrel adapter?

Yes, the battery connects to the internal motherboard header used by part numbers CC03XL, HSTNN-IB9F, L78555-005 and L77608-1C2, independent of the external charger type.

I still use an EliteBook 830 G7 — does the CC03XL replacement fit the same bay as the HSTNN-IB9F it shipped with?

The pack is listed for EliteBook 830 G7 and 835 G7 alongside the G8 models, confirming identical physical fit for the original HSTNN-IB9F bay.
