Direct replacement for Pavilion 15-cx models

This lithium-ion battery is built for HP Pavilion 15-cx0017TX, 15-cx0018TX, 15-cx0019TX, 15-cx0020TX and 15-cx0021TX notebooks. It delivers 11.55 V and 52.5 Wh through a three-cell layout. The unit is new and carries CE and RoHS certification.

Voltage and capacity are fixed by the original

The pack supplies exactly 11.55 V and 52.5 Wh, so runtime matches the factory specification. Lithium-ion chemistry degrades with age and heat; expect gradual capacity loss over hundreds of charge cycles. No higher-capacity version exists for this form factor.

Verify the exact model number before ordering

Check the label on the base of your laptop or in the BIOS to confirm it is one of the five listed variants. The connector and screw positions are model-specific and will not fit other Pavilion 15 series chassis. Installation requires removing the bottom case screws.
