Compatible Dell Latitude Models

This 7.4V 51Wh lithium-ion battery fits Dell Latitude E5250, E5450 and E5550 notebooks. It is a new 4-cell replacement designed to restore original runtime for mobile professionals and students who rely on these specific chassis. The pack carries CE and RoHS certification and includes a one-year replacement warranty.

Who This Suits and Who It Does Not

Owners of the three listed Latitude models needing a direct 7.4V 51Wh swap will find a precise fit. Buyers whose original battery shows a different voltage, cell count or shape should look elsewhere because the supplier notes two distinct, non-interchangeable packs exist for these laptops and visual confirmation is required before purchase.

Critical Voltage and Capacity Match

The single specification that decides compatibility is the 7.4V 51Wh rating combined with the 4-cell lithium-ion construction. Only batteries matching these exact electrical parameters will operate correctly in the E5250, E5450 or E5550; a different voltage or watt-hour value will prevent proper charging and system recognition.

Questions about this item

My Latitude E5450 currently runs a 4-cell pack — will this 51 Wh G5M10 battery fit without modification?

Yes, the 7.4 V 4-cell G5M10 is built for the E5250, E5450 and E5550, so it matches the original form factor and connector on those models.

I am moving the battery between an E5250 and an E5550 — will both systems recognise the 51 Wh capacity correctly?

Both the E5250 and E5550 read the battery through the same Dell SMBUS interface, so each laptop will report the 51 Wh rating and remaining run-time accurately.

After fitting the battery, how can I confirm the 51 Wh capacity is being reported by the BIOS?

Power on, enter BIOS at the Dell splash screen, and check the Battery Information page — it should show 51 Wh design capacity and 100 % health on a new pack.
