Replacement Battery for HP Pavilion

This 15.4V lithium-ion battery replaces the original pack in HP Pavilion CB001NQ, CB001NT, CB001NU, CB001NX, CB002NB and CB002NE models. It uses four premium cells to deliver 70W of capacity and is supplied new with CE and RoHS certification. A one-year replacement warranty covers defects in materials and workmanship.

Sustained Runtime Behaviour

The 70W cell configuration maintains a steady voltage output during extended work or streaming sessions, reducing the sudden drops that occur with aged packs. Consistent current delivery keeps the system stable through long document editing or video playback without unexpected throttling. The lithium-ion chemistry preserves usable capacity over hundreds of charge cycles.

Thermal and Power Characteristics

Normal operation stays within the thermal envelope of the original design, so the laptop’s existing cooling handles the pack without extra fan noise. Efficient cell balancing limits heat build-up during charging and heavy discharge. Power draw matches the factory specification, keeping AC adapter loading unchanged.

Questions about this item

Does the 15.4 V 70 W 4-cell lithium-ion battery generate noticeable heat or noise during all-day use?

The battery uses passive lithium-ion cells with no moving parts, so it produces no audible noise and only minimal warmth during extended operation.

What must the buyer already own for this 15.4 V 70 W replacement to function?

A compatible HP Pavilion model such as CB001NQ, CB001NT, CB001NU, CB001NX, CB002NB or CB002NE and the original AC adapter for recharging.

How does this 15.4 V 70 W pack behave alongside the original charger and motherboard in an older Pavilion unit?

It matches the factory voltage and cell count, so the existing charging circuit manages it normally without firmware changes or BIOS updates.
