Rectangular black lithium-ion laptop battery with two cells and label showing 41.9Wh 7.7V

TAURKENAM

TAURKENAM TF03XL 41.9Wh 7.7V 2-cell laptop battery

SKU CH-FGW5-AWGES

A 41.9 Wh, 7.7 V lithium-ion replacement battery compatible with HP Pavilion 14, 15 and 17 series laptops

  • Battery TypeLithium-Ion
  • 9 Wh capacity powers extended sessions
  • 7 V 2-cell lithium-ion matches original spec
  • Fits HP Pavilion 14, 15 and 17 series
  • Replaces TF03XL, 920070-855 and HSTNN-UB7J part numbers
  • 100 % new OEM-compatible battery ready to install

Direct replacement for HP Pavilion x360 convertibles

This lithium-ion pack replaces the original TF03XL cell in HP Pavilion 14-CD, 14M-CD, 14-BF, 14-BK, 15-CD, 15-CC, 15-CK and 17-AR series notebooks. It matches the factory voltage of 7.7V and capacity of 41.9Wh across two cells, so the laptop reports the same charge level and runtime as the stock unit. Builders restoring a convertible or clamshell model listed in the compatibility table can install it without adapter changes.

Low heat output during typical office work

The 2-cell chemistry draws modest current during web browsing, document editing and video playback, keeping internal temperatures close to the original design envelope. Fan activity remains at the baseline profile defined by the system firmware, so acoustic output does not increase compared with the factory battery. Power delivery stays steady at 7.7V, avoiding voltage sag that could throttle the processor during light multitasking.

Stable voltage through a full discharge cycle

Under sustained load such as video rendering or large file transfers, the pack maintains its rated voltage without premature cutoff, allowing the laptop to complete long tasks on battery power. The 41.9Wh capacity is consumed evenly across both cells, so runtime scales predictably with workload intensity. Users who need consistent performance away from mains power will see the same discharge curve as the OEM unit.

Questions about this item

How do I install the TF03XL battery and which step do people often miss?

Power off the laptop, disconnect the AC adapter, remove the base screws, unplug the old battery cable, fit the new 2-cell 7.7V pack, reconnect the cable, replace the base, then calibrate by charging to 100 % and discharging fully once.

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

The battery is sealed and requires no user maintenance; capacity will gradually decline with charge cycles, and the pack should be replaced when run-time no longer meets your needs.

What limit appears first on the 2-cell 7.7V unit during sustained heavy use?

The 41.9Wh capacity is the limiting factor; under continuous high load the charge depletes quickly and the pack will reach its low-voltage cutoff sooner than higher-capacity alternatives.
