  • Match the exact part number printed on your current battery, or confirm a different number in the manufacturer’s service manual.
  • Check voltage, connector, polarity, dimensions, and mounting points against the original battery.
  • Make sure the seller names your exact laptop model or variant and offers a suitable return policy.

How we know

This answer is derived from 13 independent hardware reports for the Dell Latitude E5400, of which 100% agree. We publish a model only when the reports agree overwhelmingly.

Check it yourself

On Windows, open a terminal and run powercfg /batteryreport, then open the generated HTML report — it names the battery’s model and part number. On Linux, run upower -i /org/freedesktop/UPower/devices/battery_BAT0. On any laptop, the surest method is the label printed on the battery itself, visible once you remove the back panel.

Other laptops reporting the same battery part number

These field reports contain an exact matching part number at the same observed voltage. That is useful evidence, but it does not guarantee the connector, dimensions, mounting points, firmware, or physical fit.

Battery health and replacement signs

Short runtime, unexpected shutdowns, or a large drop from design capacity can justify a closer check; a charging fault does not by itself prove the battery is worn out. See how to check battery health, judge replacement signs, or diagnose a charging problem.
