Direct replacement for HP Pavilion batteries

The TAURKENAM HT03XL is a new lithium-ion polymer battery rated at 11.55 volts and 41.7 watt-hours. It uses a three-cell design to match the original electrical specification. The unit replaces part numbers including HT03XL, HSTNN-LB8M and the L11421 series across many Pavilion models.

Upgrades worn or failed original packs

This battery fits HP Pavilion 14, 15 and 17 inch series such as 14-CE, 15-DA and 17-BY, plus Pavilion 240 G7 and 340 G5 lines. It restores full runtime when the factory pack no longer holds charge or reports a permanent failure. The jump is worth it when calibration no longer improves reported capacity.

Simple internal swap with common pitfalls

Installation requires opening the chassis and disconnecting the old pack before connecting the new one. Common issues include forgetting to detach the internal cable first, misaligning the connector pins, or leaving the battery unsecured. Verify the part number on the original label matches the supported list before starting.

A 3-cell 11.55 V 41.7 Wh polymer battery usually provides several years of daily use; capacity gradually declines with each charge cycle.
