Compatible HP ProBook models

The RR03XL lithium-ion battery fits HP ProBook 430, 440, 450, 455 and 470 G4 notebooks as well as 440, 450 and 470 G5 models. It replaces part numbers including HSTNN-PB6W, HSTNN-LB7I, 851477-421 and 851610-850. Buyers with other ProBook generations or non-HP laptops cannot use this pack.

Voltage and capacity limits

The cell chemistry delivers 11.4 V and 48 Wh, matching the original specification for the listed models. Runtime depends on the host system's power draw, screen brightness and active workloads; heavy multi-tasking or discrete graphics will reduce usable time between charges.

Upgrade from degraded originals

This pack restores mobility when the factory battery no longer holds sufficient charge for a typical work session. Grade A cells and built-in circuit protection improve output stability compared with worn units. The improvement is worthwhile when the old battery cannot sustain portable use for the required period.

Questions about this item

Which capacity version of the RR03XL should I pick for my ProBook 440 G5?

The RR03XL is offered in a single 48Wh capacity that matches the original part numbers listed for the 440 G5.

What does the 11.4V 48Wh rating mean for daily runtime on a ProBook 450 G4?

At 11.4 volts and 48 watt-hours the pack delivers the same energy as the factory HSTNN-LB7I, so expect comparable runtime per charge.

What connector standard does the RR03XL use and will it fit a ProBook 470 G4?

It uses the standard HP internal battery connector for the listed part numbers, so it fits the 470 G4 without adapters.
