3-cell Li-ion battery for HP Pavilion

This 11.55V 41.9Wh replacement battery fits HP Pavilion 14 and 15 series laptops including CE, CF and CS models. It matches part numbers such as HSTNN-LB8M and L11119-855 for a direct swap. The unit is new and built to the original form factor.

Sustained runtime and cycle life

Rated at 3630mAh, the pack delivers consistent capacity across daily charge and discharge cycles. The manufacturer states up to 600 recharge cycles before capacity drops below useful levels. Cells maintain stable voltage under typical office and media workloads.

11.55V voltage match requirement

Your laptop must accept an 11.55V battery; systems expecting a different voltage will not operate correctly with this part. Verify the original battery label before purchase. No other electrical specification determines compatibility.

Questions about this item

Does the 3-cell 41.9 Wh Li-ion pack run hotter than the original battery during all-day use?

The replacement uses the same 11.55 V chemistry and cell count as the factory unit, so thermal behaviour matches the original design under continuous load.

My Pavilion 15-CS only has the barrel charging port — will this battery connect without an extra cable?

The battery plugs directly into the internal motherboard connector used by part numbers HSTNN-LB8M and L11421-542; no external cable or adapter is required.

Will the 11.55 V pack work alongside the 20 V AC adapter I already use with my HP 250 G7?

Yes — the laptop regulates charge from the 20 V adapter down to the battery's 11.55 V rail, exactly as it did with the original pack.
