Replacement battery for HP business laptops

The PISKEKAT CC03XL is a new lithium-ion pack rated at 53 Wh and 11.55 V. It replaces the original HSTNN-DB9Q and L77608-2C1 cells used in ZBook Firefly 14 G7 and G8, EliteBook 830, 835, 840 and 845 G7 and G8, plus ProBook 635 Aero G7 and G8 models. Users should verify the exact part number printed on their old battery before ordering.

Black Li-ion cell with direct-fit connector

The battery ships in a black casing that matches the OEM form factor, so it slides into the existing compartment without adapters or cable rerouting. Its connector aligns with the motherboard header used across the listed HP series, allowing a straightforward swap once the bottom cover is removed. No additional mounting hardware or soldering is required for installation.

53 Wh capacity delivers standard runtime

At 53 Wh and 4400 mAh the pack provides the same energy budget as the factory unit, so daily office workloads see no change in unplugged endurance. Lithium-ion chemistry keeps self-discharge low during storage, and the cell operates within the thermal envelope designed for the host chassis. Normal use produces no audible noise and draws power only when the laptop requests charge.
