Replacement Battery For ProBook G6 G7

The NShi RE03XL is a new lithium polymer battery built for HP ProBook 430 440 445 450 455R G6 and 430 440 445 450 G7 notebooks. It also fits the ZHAN 66 Pro 13 14 15 G2 and ZHAN 66 Pro A 14 G3 series. The pack replaces part numbers including HSTNN-OB1C HSTNN-UB7R HSTNN-DB9A L32407-AC1 L32407-2B1 L32407-541 L32656-005.

Voltage And Connector Constraints

The cell operates at 11.55V and uses the proprietary connector keyed to the listed ProBook and ZHAN 66 models. It will not power devices that require a different voltage or a different pin layout. Buyers must match the exact part number on their original battery before ordering.

Capacity And Runtime Headroom

Rated at 45Wh and 3750mAh the pack delivers a full day of typical office work on a single charge. Heavy workloads such as sustained compilation or video export will drain it faster. Users who need multi-day autonomy without a charger should consider a higher capacity alternative if one exists for their chassis.
