Before you order, verify the replacement:
  • 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.

A part number appearing in these reports is an observation, not a guarantee that it fits every unit sold under the same model name.

How we know

This answer is derived from 20 independent hardware reports for the Dell Latitude 7440, 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.

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.
