  • Battery TypeLithium-Ion
  • 7 Wh capacity powers extended work sessions

41.7 Wh lithium-ion replacement battery

This 41.7 Wh lithium-ion battery replaces the original power pack in compatible HP Pavilion notebooks. It is built with Grade A cells rated at 11.55 V and is supplied new with two screwdrivers for fitting. The three-cell design targets users who need a direct swap for a worn or failed unit.

Replaces HT03XL, HSTNN-UB7J

The battery matches a long list of OEM part numbers including HT03XL, HSTNN-UB7J and L11119-855, covering many 14-inch, 15-inch and 17-inch Pavilion models. The jump is worth it when the original pack no longer holds charge or shows swelling. It is not for buyers who need a higher-capacity pack or a different voltage.

Two screwdrivers included for straightforward

The package includes two screwdrivers so the bottom case can be removed and the battery exchanged without extra tools. The common issue is forgetting to disconnect the internal cable before lifting the old pack, which can damage the connector. Follow the service manual for your specific model to avoid cable strain.
