Compatible HP ProBook models

This 48Wh lithium-polymer battery replaces the RR03XL and matches several HP part numbers including HSTNN-LB7I and 851477-421. It fits ProBook 430 G4 and G5, 440 G4 and G5, 450 G4 and G5, 455 G4 and G5, 470 G4 and G5, plus ZHAN 66 Pro G1 units. The black pack delivers 11.4V and 4210mAh for direct drop-in installation.

Installation and system fit

The battery slots into the existing compartment without adapters, freeing the AC adapter for travel or desk use. It supports the listed HSN-Q01C through HSN-Q08C chassis codes, so the original latch and connector align exactly. Buyers needing a different voltage, a higher capacity or a form factor for non-ProBook models will not be served by this part.

Thermals and power behaviour

Li-polymer chemistry runs at 11.4V with a 48Wh rating, so heat output stays consistent with the factory pack during typical office workloads. No active cooling is required and the cell produces no audible noise. The unit draws power only when the laptop is unplugged, leaving the charger idle and reducing overall system power draw.
