53 Wh replacement battery for HP notebooks

This 11.55 V lithium-polymer pack delivers 53 Wh of capacity and fits HP ZBook Firefly 14 G7 G8, EliteBook 830 835 840 845 G7 G8 and ProBook 635 Aero G7 G8 models. It replaces part numbers including CC03XL, HSTNN-DB9Q and L77608-2C1. Buyers needing a different capacity or screw-hole layout should verify the original battery before ordering.

Sustained runtime from a 53 Wh cell

The 4400 mAh lithium-polymer chemistry supports up to 500 recharge cycles over the life of the battery. Under continuous workloads the cell maintains stable voltage output without the rapid fade seen in lower-capacity alternatives. This makes it suitable for mobile professionals who need reliable power through a full working day.

Black polymer housing with model-specific mounting

The pack uses a black finish and screw-hole positions that match the listed CC03XL variants exactly. Because two incompatible CC03XL versions exist, the precise hole alignment prevents installation errors on the supported EliteBook, ZBook and ProBook chassis. No adapters or modifications are required for the compatible models.

Questions about this item

Does the 53Wh lithium-polymer cell run hot or draw extra power during a full workday?

The battery simply stores energy; heat and power draw come from the laptop itself. Normal use stays within the cell's 11.55V design limits.

My HP EliteBook 840 G8 originally used part number L77608-2C1 — will this CC03XL fit without any extra brackets or cables?

Yes. L77608-2C1 is listed among the replaced part numbers, so the battery matches the original connector and screw-hole layout exactly.

I still have an older ProBook 635 Aero G7 — will the 4400mAh capacity work the same as the factory pack?

The 53Wh / 4400mAh rating matches the original specification for the G7 and G8 series, giving equivalent run-time per charge.
