Matching Part Numbers

The supplier lists these replacement part numbers: KM769, RM656 and T749D. This battery fits Dell Latitude E5400, E5410, E5500 and E5510 laptops. Match the part number on your old pack with KM742 before ordering, and check the model name under your laptop.

Signs the Battery Needs Replacing

Typical signs include very short runtime, sudden shutdowns while the meter shows charge, a percentage that jumps, or a laptop that runs only while plugged in. These show that the pack is worn.

Why Replace It Early

A weak battery makes a laptop unreliable for classes, meetings and travel. Unexpected power loss can also corrupt files, so replacing the pack early protects your work and your time.

What You Get

You receive one Dell KM742 battery pack for the models above, ready to fit in place of your old pack. The supplier does not list the capacity or voltage, so if you are unsure about your model, send us the name printed under your laptop and our Elephant Road team will check the fit for you before you buy, so you avoid a wrong order and a second trip to the shop.

Care Tips for Longer Life

Avoid draining the battery to zero, keep the laptop away from heat while charging, and use a quality charger. If the laptop stays plugged in for long periods, discharge it to about half once a month, which slows capacity loss.
