41.5 Wh replacement battery for Pavilion 14

This lithium-ion pack delivers 41.5 Wh at 11.55 V in a black housing. It matches the SE03XL form factor and replaces part numbers including HSTNN-LB7G, 31CP6/60/80 and 849568-421. Owners of listed Pavilion 14 models can swap the original unit without modification.

Steady output through a full workday

The cell chemistry maintains consistent voltage under continuous load rather than spiking for short bursts. Typical office tasks, web browsing and video playback draw power evenly, so the pack runs cooler and avoids the rapid capacity drop seen in aged originals. A 12-month warranty backs the replacement.

Direct swap for worn or failed originals

The battery fits the extensive model list from E8Q01EA through Pavilion 14-AL006NF and later variants sharing the same chassis. Upgrading makes sense when the original no longer holds charge through a meeting or commute. It is not for users needing higher capacity than 41.5 Wh or a different voltage platform.

Questions about this item

Does the 11.55V 41.5Wh SE03XL battery run hot or draw extra power during all-day use?

It is a standard 11.55V 41.5Wh lithium-ion pack; heat and power draw match the original HSTNN-LB7G specification.

What must my Pavilion 14 already have inside for this 31CP6/60/80 battery to connect and work?

Your laptop needs the original battery connector and mounting points used by part numbers 849568-421 or 849908-850.

Will this SE03XL replacement behave the same as the aged HSTNN-UB6Z battery I am removing from my Pavilion 14-al000?

Yes, it restores the factory 11.55V 41.5Wh capacity and fits the same bay as the old HSTNN-UB6Z unit.
