Replacement Battery for HP Pavilion Laptops

The FOCUSTEC TF03XL is a new lithium-polymer battery rated at 11.55V and 41.9Wh across 3 cells. It replaces part numbers including TF03XL, 920070-855, 920046-421 and HSTNN-LB7X. The pack ships with a screwdriver set so you can swap the old unit without sourcing tools separately.

Upgrading from a Depleted Original Pack

When the factory-fitted cell no longer holds a useful charge — typically after several hundred cycles — this unit restores the original runtime. The jump is worth it if your notebook now shuts down early, throttles on battery or only runs while plugged in. It is not for buyers who need a higher-capacity design than the stock 41.9Wh specification.

Behaviour Under Sustained Load

Grade-A cells and built-in circuit protection keep voltage stable during extended discharge rather than sagging after a short burst. The manufacturer rates the pack for up to 500 recharge cycles over its service life. It is not for users who require hot-swap capability or an external charging cradle.
