Replacement Battery for HP Laptops

This new 3-cell lithium-ion battery delivers 11.55V and 53W of capacity for compatible HP notebooks. It replaces part numbers L77608-271, L77608-421, L77608-1C1, L77608-2C1 and L78555-005. The unit is built for users who need a direct replacement to restore mobile runtime.

Critical Model Variation Warning

The CC03XL designation covers two distinct physical models that are not interchangeable. The supplier notes that buyers must compare their original battery against the product photo before ordering to ensure the correct fit. No software or accessories are bundled; the difference is purely mechanical and electrical.

Straightforward Internal Swap

Installation requires opening the laptop chassis to access the internal battery compartment. The main risk is ordering the wrong CC03XL variant, which will not connect or seat properly. Verifying the exact part number on the old battery prevents this mismatch. CE and RoHS certifications confirm safety compliance.

Questions about this item

How many cells does the 53W CC03XL pack contain and what chemistry is used?

The pack uses three lithium-ion cells to deliver its 53 watt-hour rating.

What voltage mismatch would prevent this battery from fitting my HP laptop?

It is built for 11.55 V systems; a laptop requiring a different voltage will not accept it.

Does the 3-cell design run hotter or louder than higher-cell alternatives during all-day use?

The battery itself produces no noise and generates only normal warmth; sustained heat depends on the laptop's own cooling design.
