FOCUSTEC AR08 8-cell replacement battery

The FOCUSTEC AR08 is an 8-cell lithium-ion battery built to replace the original power pack in HP ZBook 15 and 17 mobile workstations. It matches part numbers including HSTNN-IB4H, HSTNN-IB4I, 708456-001 and 708455-001. The unit is supplied new and ready to install.

Drop-in fit for ZBook 15 and 17 series

This battery slots directly into the existing bay on HP ZBook 17, ZBook 17 G1, ZBook 17 G2 and ZBook 15 mobile workstation models. No adapter cables or firmware updates are required. Swapping the old pack restores full mobile operation without tying the machine to a wall outlet.

77 Wh capacity for extended work sessions

Rated at 14.8 V and 5200 mAh, the 77 Wh pack delivers hours of untethered run time for typical office and field workloads. Heavy multi-core rendering or sustained GPU compute will drain the charge faster. Users who need all-day autonomy without recharging should consider a second battery or a high-capacity power bank.
