Replacement battery for Latitude E5250 E5450 E5550

This KingSener G5M10 unit is a 7.4V 51WH lithium-polymer pack built to replace the original Dell battery in Latitude E5250, E5450 and E5550 notebooks. It arrives new and includes a fitting tool for the swap. The black housing matches the OEM colour scheme.

Capacity choice among three Dell variants

Dell ships the E5450 and E5550 with three different packs: a 38WH RYXXH, this 51WH G5M10, and a 62WH R0TMP. The G5M10 sits in the middle, so it will not deliver the longest runtime nor the lightest weight. Buyers who need maximum capacity should verify their original part number first.

Straightforward swap with the included tool

Installation consists of releasing the latch, removing the old pack and clicking the new one into the same bay. The supplied tool helps with stubborn screws. The main risk is ordering the wrong capacity code — G5M10, RYXXH or R0TMP — so confirm the label on the original battery before purchase.

Questions about this item

How do I know whether the 51WH G5M10 is the correct battery for my Latitude instead of the 38WH or 62WH versions?

Check the part number on your original battery; if it reads G5M10, 7V69Y, TXF9M, 79VRK or 07V69Y then this 51WH pack is the direct replacement for Latitude E5250, E5450 or E5550.

What runtime difference should I expect from the 51WH rating compared with the smaller 38WH option?

The 51WH capacity stores roughly one-third more energy than the 38WH alternative, so typical use on a Latitude E5450 or E5550 will last proportionally longer between charges.

Does the 7.4V lithium-polymer pack use the standard Dell battery connector for the Latitude E5250 series?

Yes, the G5M10 is built to the original Dell pin-out and voltage for Latitude E5250, E5450 and E5550, so it fits the existing battery bay without adapters.
