41.9 Wh replacement battery for HP Pavilion

The FOCUSTEC TF03XL is a new 41.9 Wh lithium-polymer battery rated at 11.55 V with three cells. It replaces part numbers such as 920070-855 and 920046-421 in compatible HP Pavilion notebooks. The package includes the battery, two screwdrivers and an instruction sheet.

Suits owners of listed HP Pavilion models needing

This unit fits the extensive series of HP Pavilion 14, 15 and 17 inch models enumerated in the compatibility data, including x360 convertibles. It is not for users whose laptop requires a different voltage, cell count or connector, or for anyone needing a higher-capacity pack than 41.9 Wh.

41.9 Wh capacity decides runtime

The 41.9 Wh rating is the single figure that determines how long the system runs on battery power. If your workflow demands more energy per charge, this capacity will fall short; if it matches the original specification, the TF03XL restores factory-equivalent endurance.

Questions about this item

Does the TF03XL battery require any calibration or conditioning cycles after installation?

The lithium polymer cells in the 41.9Wh pack do not need scheduled calibration; normal charge and discharge cycles maintain accuracy.

Which component of the 3-cell 11.55V pack reaches its limit first during continuous heavy load?

The three lithium polymer cells share the 41.9Wh capacity equally, so cell voltage sag under sustained draw is the first limiting factor.

How much heat does the TF03XL generate when the laptop runs all day on battery power?

The 11.55V 3-cell design produces minimal heat during typical use; the pack stays near ambient temperature inside the HP Pavilion chassis.
