Direct Replacement for HP TF03XL

This 11.55V lithium-ion battery replaces HP part numbers TF03XL, TF03041XL, TF03041, 920070-855, 920046-121 and 920070-856. It is built for owners of those specific HP laptops who need a new power source that fits the original bay without modification.

42 Wh Capacity with Three-Cell Design

The 42 Wh rating delivers a practical runtime for daily office tasks, web browsing and media playback. Heavy workloads such as sustained video editing or gaming will drain the pack faster, so users who regularly run demanding applications should keep a charger nearby.

CE and RoHS Certified with One-Year Coverage

Certification confirms compliance with European safety and environmental standards for lithium-ion cells. The supplier backs the unit with a one-year replacement warranty against defects in materials or workmanship, giving buyers a defined period of protection after purchase.

Questions about this item

Will this 3-cell 11.55 V 42 W battery fit the same bay as my original HP TF03XL unit?

Yes — it is built to match the TF03XL, TF03041XL and TF03041 form factor so it slides into the existing compartment without modification.

How can I confirm the battery is charging correctly after installation?

The laptop’s power indicator should show a charging icon and the OS battery report will read 11.55 V design voltage with a 42 Wh full-charge capacity.

Does the package include any screws, cables or tools, or must I source them separately?

Only the battery itself is supplied; mounting screws and any ribbon cables are reused from the old unit.
