Replacement battery for HP Pavilion and Omen

This GreenTech SR03XL battery fits HP Pavilion 15-DC, Pavilion 17-CD and Omen 15-DC laptops. It is a three-cell lithium-ion pack rated at 11.55V and 52.5WHR with a capacity of 4545mAh. The unit is brand new and carries CE, FCC and RoHS safety certifications.

Upgrading from a worn original pack

It replaces OEM part numbers SR03XL, L08855-855, SR03052XL, L08934-1B1 and HSTNN-IB8L. The jump is worth it when the original battery no longer holds a useful charge or shuts down under load. Buyers who need a higher capacity than 52.5WHR cannot be served by this model.

Straightforward internal swap

Installation requires opening the laptop chassis and disconnecting the old pack before fitting the new one. Most issues arise from loose connector seating or forgetting to disable the internal battery in the BIOS before starting. No soldering or firmware updates are involved.

Questions about this item

What are the exact OEM part numbers this SR03XL battery replaces in my HP Pavilion or Omen laptop?

This GreenTech SR03XL replaces OEM part numbers SR03XL, L08855-855, SR03052XL, L08934-1B1 and HSTNN-IB8L across the listed HP Pavilion 15-DC, 17-CD and Omen 15-DC models.

Which screw locations or cable connectors must I disconnect when swapping the internal 3-cell pack in an HP Pavilion 15-DC?

Remove the bottom case screws, disconnect the battery cable from the motherboard header, then unscrew the battery retention screws before lifting the 11.55 V 4545 mAh pack out.

What capacity loss should I expect from the 52.5 Wh lithium-ion cells after extended daily use?

The 3-cell 11.55 V 4545 mAh lithium-ion pack will gradually lose capacity over hundreds of charge cycles; capacity decline is normal for this chemistry.
