Direct replacement for Dell XPS 15 9530 9535

This 91Wh lithium-polymer battery replaces part numbers 245RR and TOTRM. It fits Dell XPS 15 9530, XPS 15 9535, Precision M3800 and P31F models. The unit delivers 11.1V and 7810mAh capacity in a black finish. It is supplied brand new and ready for installation.

Simple swap with basic tools and no soldering

Remove the bottom case screws, disconnect the old pack and connect the new one using the original cable. Most users finish in under 30 minutes with a small Phillips driver. Common issues are stripped case screws and forgetting to reconnect the battery cable before reassembly. Ensure the connector seats fully or the system will not recognise the pack.

Verify your exact model number

Check the service tag or BIOS for XPS 15 9530, 9535, Precision M3800 or P31F. Confirm the original battery label reads 245RR or TOTRM. This pack will not fit other Dell 15-inch chassis or Precision models with different part numbers. Buyers who need a higher-capacity option or a different voltage should look elsewhere.
