Replacement Battery for Dell Latitude E5450 E5550

This 7.4V 51Wh lithium-polymer battery replaces Dell part numbers G5M10 8V5GX R9XM9 WYJC2 1KY05. It fits Latitude 14 E5450, Latitude 15.6 E5550 and Latitude 12 E5250 series notebooks. The cell is new from the manufacturer and carries CE, FCC and RoHS safety certifications.

Simple Swap with Built-In Cable

Installation requires removing the bottom cover and disconnecting the old pack, then plugging the new battery into the same motherboard header. No soldering or firmware update is needed. The most common issue is a loose connector after reassembly; ensure the latch clicks fully before closing the case.

Verify Part Number and Connector Layout

Before ordering, confirm the original battery carries one of the listed part numbers and matches the physical connector orientation shown in product images. This pack is not compatible with Latitude models outside the E5450, E5550 and E5250 series. Buyers needing a higher-capacity cell or a different voltage should look elsewhere.

Questions about this item

How can I confirm the 7.4V 51Wh Li-polymer battery is working correctly after installing it in my Dell Latitude E5450?

After installation, power on the laptop and check the battery icon in Windows; it should show the new pack charging and report a design capacity close to 51Wh in the battery report.

What is included in the box with the G5M10 8V5GX R9XM9 WYJC2 1KY05 battery and do I need to buy any tools or cables separately?

The package contains the replacement battery only; no screwdrivers, cables or additional hardware are supplied, so have a suitable Phillips screwdriver ready for the swap.

Which part-number version should I choose for a Dell Latitude 15.6 E5550 versus a Latitude 12 E5250?

The single part number G5M10 8V5GX R9XM9 WYJC2 1KY05 fits all listed models — Latitude 14 E5450, 15.6 E5550 and 12 E5250 — so no separate version selection is needed.
