HP Pavilion 11.55V 42W 3-Cell Battery

This replacement lithium-ion battery supplies 11.55V and 42W capacity for HP Pavilion 14, 15 and 17 series laptops. It fits models including 15-CC, 15-CD, 15-CK, 14-CD, 14M-CD, 14-BF, 14-BP, 14-BK and 17-AR. The three-cell design targets users whose original pack no longer holds a useful charge.

Replaces worn original packs

Swapping a depleted factory battery restores full runtime when the old unit drops below 100% health or shuts down under load. The upgrade is worth it when daily unplugged use is cut short or the system throttles due to voltage sag. Buyers who need more capacity than 42W or a different voltage should look elsewhere.

Simple internal swap

Installation requires opening the chassis, disconnecting the old pack and connecting the new one using the matching connector. Common issues are forgotten screws, reversed polarity on the connector or failing to calibrate the fuel gauge after first use. CE and RoHS markings confirm compliance with safety and environmental standards.
