SKU CH-6HEM-TQJWP

A 41.9 Wh, 7.7 V, 2-cell lithium-ion replacement battery compatible with HP Pavilion 14, 15 and 17 series laptops

  • Battery TypeLithium-Ion
  • 9Wh capacity powers extended work sessions
  • 7V lithium-ion chemistry matches original specifications
  • 2-cell design fits slim HP Pavilion chassis
  • Replaces TF03XL, 920070-855 and HSTNN-UB7J part numbers

Compatible HP Pavilion models

This lithium-ion battery replaces the original TF03XL unit in HP Pavilion 14-BF, 14-BK, 14-CD, 14M-CD, 15-CC, 15-CD, 15-CK and 17-AR series laptops. It matches part numbers including 920070-855, 920046-421 and HSTNN-UB7J. The pack is supplied new and ready to install.

Sustained load behaviour

Rated at 41.9Wh with a 7.7V output across two cells, the pack delivers consistent voltage during extended work sessions. Lithium-ion chemistry maintains stable discharge without the voltage sag seen in aged cells, supporting typical office and media workloads until the low-battery threshold triggers system sleep.

Practical interface limits

The battery connects through the proprietary HP Pavilion socket used by the listed series, so it fits only those chassis designs. No adapter or cable modification can make it work with other HP families or third-party laptops. Capacity is fixed at 41.9Wh and cannot be expanded by adding cells or external packs.

Questions about this item

Does the 7.7 V 41.9 Wh TF03XL run cooler than the original battery during all-day use?

The lithium-ion 2-cell design matches the factory voltage and capacity, so thermal behaviour stays within the laptop’s original specifications.

What laptop model must I already own for this TF03XL to fit and connect?

It replaces the original battery in HP Pavilion 14-BF, 14-BK, 14-CD, 14M-CD, 15-CC, 15-CD, 15-CK and 17-AR series notebooks listed in the compatibility data.

Will the TF03XL charge correctly in a Pavilion 15-CC that still uses the stock 41.9 Wh battery?

Yes — the 7.7 V 2-cell pack uses the same part numbers (TF03XL, 920070-855, HSTNN-UB7J) as the factory unit, so the charging circuit recognises it normally.
