Dell Latitude E5400/E5500 Series Replacement

This 6-cell lithium-ion battery replaces the original pack in Dell Latitude E5400, E5410, E5500 and E5510 laptops. It delivers 11.1 volts and 5200 milliampere-hours for 58 watt-hours of capacity. The unit is new and built with grade-A cells that meet OEM specifications.

Upgrade From Worn Original Pack

Swap this in when the factory battery no longer holds a charge through a typical work session. The 6-cell design restores the runtime the system shipped with, so the jump is worth it if your current pack drains in under two hours. It also replaces dozens of Dell part numbers including KM742, KM769, RM656 and T749D.

Check Latch And Connector Orientation

Before ordering, confirm your laptop is a Latitude E5400, E5410, E5500 or E5510 model. Verify the old battery carries one of the listed part numbers such as 312-0762 or 451-10616. Ensure the battery bay latch and wiring connector match the 6-cell form factor shown in the product images.
