Compatible Dell Latitude Models

This 4-cell lithium-ion battery is designed for Dell Latitude E5450, 5250, E5550 and 5550 notebooks. It delivers 51 Wh at 11.1 V and carries CE and RoHS certification. The unit is supplied new with a one-year warranty and is intended for owners of those specific Latitude models who need a direct replacement. It is not for buyers who need a battery for other Dell series or a higher-capacity pack than the 51 Wh rating.

Installation Notes

Replacement requires removing the bottom case screws and disconnecting the original pack before fitting this unit. The supplier stresses that two different batteries exist for these Latitude models and they are not interchangeable, so you must compare your original battery with the product photos to confirm the physical layout matches. No tools or wiring modifications are included. If the connector or screw-hole pattern differs, the battery will not seat correctly.

Pre-Order Checks

Verify the exact model number on your laptop chassis and the part number printed on your existing battery before ordering. Confirm the original pack is rated at 38 Wh or 51 Wh and uses an 11.1 V 4-cell lithium-ion design. Ensure the connector orientation and mounting holes line up with the images provided. This unit will not fit Latitude models outside the E5450, 5250, E5550 and 5550 range.

Questions about this item

How do I confirm the battery is working correctly after installing it in my Latitude E5450?

After installation, the battery should charge to 100% in the operating system and hold a stable 11.1V output. A healthy 51Wh capacity will deliver several hours of runtime on the E5450, E5550 or 5250 models under normal use.

What comes in the box and do I need to buy any extra cables or tools for my Latitude 5550?

The package contains the 4-cell lithium-ion battery unit only. No additional cables, screws or tools are required; it fits directly into the existing battery bay of the Latitude 5550, 5450 and 5250.

My Latitude 5250 shows two battery options — how do I pick the right version?

Match the original battery's part number and physical shape to the product photos. This 38Wh 11.1V 51Wh 4-cell unit replaces the specific variant shown; the alternative version has a different connector layout and will not fit.
