Compatible HP Pavilion Series

This lithium-ion battery replaces the HT03XL and L11119-855 part numbers across multiple HP Pavilion models. It fits 14-inch, 15-inch and 17-inch chassis including the 14-CE, 14-CF, 15-CS, 15-DA, 15-DB, 17-BY and 17-CA series. The unit also covers Pavilion 240, 245, 250, 255, 340 and 348 variants.

Normal Thermals and Power

Lithium-ion chemistry delivers stable voltage during typical office and web workloads without generating excess heat. The cell pack operates within the thermal envelope designed for the original HP chassis. No active cooling is required and acoustic output remains at zero decibels.

Sustained Load Behaviour

Under continuous discharge the pack maintains consistent output until the protection circuit engages at the low-voltage threshold. Capacity fade follows standard lithium-ion ageing curves over repeated full cycles. The battery is not designed for hot-swap operation while the laptop is running.

Questions about this item

How do I install the HT03XL L11119-855 battery in my HP Pavilion 15-DA, and which step causes the most issues?

Power off the laptop and unplug the AC adapter. Remove the bottom case screws, then disconnect the old battery cable from the motherboard before lifting it out. The step most people get wrong is forgetting to unplug the battery connector first, which can cause a short circuit.

What maintenance or replacement will the HT03XL lithium-ion battery need later?

The lithium-ion pack requires no scheduled maintenance. It will need replacement once its capacity degrades to the point where runtime no longer meets your needs, typically after several hundred charge cycles.

What limit appears first during sustained use of this replacement battery?

The first limit under sustained load is thermal. As the pack heats up during continuous discharge, the built-in protection circuit will throttle output or shut down to prevent overheating, reducing available runtime until it cools.
