What this battery replaces

This Junchi HT03XL is a new 41.9Wh 11.55V lithium-ion pack built to replace HP part numbers HT03XL, HTO3XL and L11119-855. It fits a long list of HP Pavilion 14-inch, 15-inch and 17-inch models including the 15-CS, 15-CW, 15-DA, 15-DB, 15-DW, 15-DY, 14-CE, 14-DK, 14-DQ, 14M-DH, 17-BY and 17-CA series. The three-cell design matches the original form factor for direct installation.

Cycle-life limit of lithium-ion chemistry

The supplier rates the pack for up to 500 recharge cycles over its lifetime. After that point capacity will have faded enough that run-time drops noticeably and the battery should be replaced again. The 3630mAh rating at 11.55V defines the energy available per cycle; no higher-capacity version of this exact part number is offered.

When the upgrade is worth it

Swapping in this unit makes sense when the original HP battery no longer holds a useful charge or has swollen. It restores the factory runtime specification rather than extending it. Buyers who need more capacity than 41.9Wh or a different voltage will need a separate higher-capacity kit that is not this part number.

Questions about this item

Should I pick the 41.9Wh or a different capacity for my HP Pavilion?

This battery is supplied as a single 41.9Wh 3-cell unit; there are no alternative capacities listed for the HT03XL part number.

What does 41.9Wh mean for daily runtime on my laptop?

At 11.55V and 3630mAh the pack stores 41.9 watt-hours, so a system drawing 15W would run roughly 2.8 hours before recharge.

Does the battery connector follow a standard that limits charging speed?

The HT03XL uses the proprietary HP L11119-855 connector; charging rate is governed by the laptop's internal controller, not by an open standard.
