Compatible Dell Latitude models

This 51Wh lithium-polymer battery replaces the G5M10 type in Dell Latitude E5450, E5550 and E5250 series laptops. It fits the 14 inch 5000 P48G and 15.6 inch 5000 P37F chassis. Buyers needing the 38Wh RYXXH or 62Wh R0TMP variants cannot use this pack.

Capacity and voltage match

The single specification that decides fit is the 51Wh capacity at 7.4V across four cells. Only systems originally equipped with a 51Wh G5M10 battery are supported; 38Wh and 62Wh configurations are electrically incompatible.

Thermal and power behaviour

Normal operation stays within the cell chemistry limits for 7.4V Li-Polymer packs. The integrated protection circuit guards against short circuit, over-voltage, over-current and deep discharge. No active cooling is required and acoustic noise is absent.
