Who this suits and who should look elsewhere

Owners of the listed Latitude models who need a direct swap for a worn or failed original battery will find the correct voltage and connector here. Buyers with other Dell series or non-Dell laptops cannot use this pack because the part numbers and form factor are specific to the E5450, E5550 and E5570 lines.

Fitting into your laptop

The battery slots into the existing bay without tools and uses the original charging circuit. No BIOS update or additional hardware is required. One battery is included in the package, freeing you from sourcing separate cables or adapters.
