15.4 V 70 W replacement battery

This lithium-ion pack is built for HP Pavilion 15-cb030ng, 15-cb031ng, 15-cb032ng, 15-cb033ng, 15-cb035ng and 15-cb035wm notebooks. It restores original run-time for owners whose factory cell has faded. The four-cell design fits the existing bay without modification.

Voltage and cell-count limits

The pack delivers 15.4 V from four lithium-ion cells, matching the laptop's native rail. Capacity is fixed at 70 W, so heavy loads will drain it faster than lighter workloads. No higher-voltage or higher-cell-count option exists for these chassis.

Capacity and practical headroom

The 70 W rating supports typical office tasks, streaming and web browsing for several hours. Intensive rendering, gaming or sustained CPU loads will exhaust the charge more quickly. Users needing all-day autonomy away from mains power should plan for a second pack or a USB-C power bank.
