Direct replacement for HP Pavilion series

The PISKEKAT TF03XL is a 2-cell lithium-ion battery rated at 7.7V and 41.9Wh. It matches part numbers TF03XL, TF03041XL, 920070-855 and 920046-421 for 100% OEM compatibility. The unit fits HP Pavilion 14-BF, 14-BK, 14-CD and 14M-CD models as well as 15-CC, 15-CK, 15-CD and 17-AR series laptops. Condition is new and ready for immediate installation.

Thermal behaviour and power delivery

Lithium-ion chemistry keeps internal resistance low during normal discharge so the pack runs cool under typical workloads. Voltage remains stable at 7.7V across the capacity range, delivering consistent power without sudden drops. The 41.9Wh rating supports extended unplugged sessions for the compatible 14, 15 and 17 inch Pavilion chassis. No active cooling or fan interaction is required.

Fitment assurance and part-number cross-reference

The bundle includes only the battery itself; no tools, screws or software are supplied. Compatibility is verified against an extensive list of part numbers including HSTNN-UB7J, HSTNN-LB7L and TPN-Q190 through TPN-Q196. Buyers whose laptop uses a different part number or a 3-cell variant will need a separate SKU. The 30-day return window and 12-month replacement cover fitment errors or early failure.

Questions about this item

How do I install the TF03XL 2-cell 7.7V battery in my HP Pavilion 14-CD series and what step is often missed?

Power off the laptop, unplug the AC adapter, remove the bottom case screws, disconnect the old battery cable from the motherboard, fit the new pack, reconnect the cable securely, then reassemble; the step most often missed is reconnecting the battery cable before closing the case.

What maintenance or replacement will the 41.9Wh Li-ion pack need later?

The 2-cell Li-ion pack will gradually lose capacity over repeated charge cycles; plan to replace it once runtime no longer meets your needs, as no user-serviceable parts exist inside.

What limit appears first on the 7.7V 41.9Wh battery during sustained heavy use?

Under continuous high load the pack will hit its thermal and voltage sag limits first, causing the laptop to throttle performance or shut down to protect the cells.
