Compatible HP ProBook replacement

This 11.4V lithium-ion battery replaces part numbers RR03XL, RR03048XL and multiple HP spares including 851477-421, 851477-541, 851477-831, 851477-832, 851610-850 and 851610-855.

Suits owners of listed G4 notebooks

Buyers with a ProBook 430, 440, 450, 455 or 470 G4 or an mt20 can use this pack as a direct swap for the original battery. Users of other HP series, different generations or non-HP laptops should look elsewhere because the connector and form factor are specific to these models. The battery is not intended for devices that require a different voltage or capacity rating.

Drops into the existing battery bay

Installation uses the laptop’s own bay and latch mechanism so no extra brackets, cables or tools are needed. The 11.4V output matches the system’s power rail and the 48Wh capacity restores original run-time without changing the charger or power settings. The pack frees the user from a worn-out cell while keeping the stock thermal and mechanical design intact.
