Replacement battery for HP Pavilion series

This lithium-ion battery replaces the original power source in compatible HP Pavilion 14, 15 and 17 inch laptops. It is built from new cells and a smart protection circuit. The black pack fits models such as the 15-cu1xxx, 15-cw1xxx and 17-by0xxx ranges. Owners of other notebook families cannot use this part.

Voltage and capacity match the original spec

The cell delivers 11.4V and 41.04Wh, which equals 3600mAh at the rated voltage. These figures must match the label on the battery you are removing; a different voltage or watt-hour rating means the pack is not suitable. No other electrical parameter determines compatibility.

Runs cool with no moving parts

The battery produces no fan noise because it has no active cooling. Heat output stays low during normal charge and discharge cycles. Power draw is limited to the laptop's own management system, so the pack does not add thermal load beyond the original design.

Questions about this item

What does the 41.04Wh rating mean for daily use on my HP Pavilion?

The 41.04Wh capacity at 11.4V stores enough energy for several hours of typical office work or web browsing before the laptop needs recharging.

Which connector standard does the HT03XL use and what does it limit?

It uses the HP-specific multi-pin connector that matches part numbers such as HSTNN-DB8R and L11119-855, so it only fits laptops designed for that exact interface.

Will this battery physically fit my 15-cu1xxx or 17-by0xxx chassis?

Yes, the pack is built to the dimensions of the original HT03XL and replaces part numbers including L11421-542 and TPN-Q207, which are used in those series.
