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 6 independent hardware reports for the Dell Latitude 5550, 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.
