Compatible HP Pavilion models

This replacement battery fits HP Pavilion 14-BF120TU, 14-BF125TX, 14-BF146TX, 14-BK0XX and 14-BK061ST laptops. It is a lithium-ion pack rated at 11.55V and 42W with three premium cells. The unit is supplied new and carries CE and RoHS certification.

Sustained power delivery

The 42W capacity supports consistent output during extended work or streaming sessions. Lithium-ion chemistry maintains stable voltage across the discharge cycle, reducing sudden shutdowns under load. Rigorous testing targets long-term reliability rather than short burst performance.

Straightforward battery swap

The pack is shaped for direct insertion into the listed Pavilion chassis, so no adapter or cable modification is required. Users should discharge the old pack before removal and charge the new one fully on first use. Buyers who need a different voltage or a higher cell count cannot use this unit.

Questions about this item

How much heat or noise does the 11.55V 42W lithium-ion battery produce when the laptop runs all day?

The battery itself has no moving parts and generates no audible noise; normal warmth during extended use is typical for lithium-ion cells.

What must I already own for this 3-cell replacement to work in my Pavilion?

You need one of the listed HP Pavilion models — 14-BF120TU, 14-BF125TX, 14-BF146TX, 14-BK0XX or 14-BK061ST — and the original battery compartment intact.

Will the 11.55V 42W pack function alongside the original charger and aging motherboard in an older Pavilion unit?

Yes, the voltage and connector match the factory specification, so the existing AC adapter and system board will recognise and charge the pack normally.
