2-power 2P-3477W - 35,6 cm (14)

Where generic replacements cut corners, the 2-POWER 2P-3477W steps in as a purpose-built power source for HP ProBook 440 G0/G1, 450 G0/G1 and 470 G0/G1 notebooks. Its 6-cell lithium-ion core delivers a stable 10.8 V output and 4400 mAh capacity, giving you 48 Wh of usable energy per charge cycle. That means fewer interruptions during long work sessions, less time tethered to a wall outlet, and a battery that behaves like the original HP unit it replaces.

Highlights

• Direct replacement for HP part numbers HSTNN-LB4K, HSTNN-UB4K, H6L28AA, H6L28ET, HSTNN-IB4K and HSTNN-DB4K
• 6-cell lithium-ion chemistry for high energy density and consistent discharge performance
• Integrated protection against overcharge, over-discharge, overcurrent and short circuit
• CE and RoHS certified; backed by a 12-month warranty
• Black housing matches the original battery bay design

In daily use

Installation is straightforward: power down the ProBook, release the latch, slide out the old pack and click the 2P-3477W into place. Once seated, the battery communicates with the laptop's charge controller to provide accurate remaining-time estimates. Expect full recharge cycles to complete in roughly the same time as the OEM pack, with no special calibration required. The 4400 mAh capacity is well suited to mixed workloads — document editing, web browsing, video conferencing and light multitasking all fall within a comfortable single-charge range. For users who keep a spare battery on hand, this unit's low self-discharge rate means it stays ready even after weeks in a laptop bag.
