Compatible Dell XPS 15 9550 replacement

This lithium-ion battery fits Dell XPS 15 9550 and Precision 5510 series laptops. It replaces part numbers M7R96, 62MJV, 1P6KD and 31CP7/74/64. The black pack delivers 11.4 volts and 56 watt-hours of capacity. Buyers with other Dell models should verify the original part number before ordering.

Simple internal swap with connector care

Installation requires opening the chassis and disconnecting the original pack before fitting the new unit. The connector is keyed, so align it carefully to avoid bent pins. Most issues come from rushing the cable routing or forgetting to secure the retention screws. Take photos of the cable path before removal for easy reassembly.

56Wh capacity defines runtime fit

The 56 watt-hour rating determines how long the laptop runs on battery power. If your original battery was rated lower, this unit may last longer; if it was higher, expect reduced runtime. Voltage is fixed at 11.4 volts and must match the original specification exactly.

Questions about this item

How do I verify the 11.4V 56Wh battery is working after installing it in my XPS 15 9550?

The system BIOS should detect the new pack and report the correct 11.4V voltage and 56Wh design capacity; Windows Battery Report will show matching figures and a healthy charge cycle count.

What comes in the package and do I need any extra parts for my Precision 5510?

The box contains only the 1x Black Li-ion battery; no tools, screws or cables are included, but the original hardware from your Precision 5510 is reused during the swap.

Which replacement part number should I match — M7R96, 62MJV, 1P6KD or 31CP7/74/64 — for my XPS 15 9550?

Any of those part numbers (M7R96, 62MJV, 1P6KD, 31CP7/74/64) identifies the same 56Wh 11.4V pack; match the code printed on your original battery to confirm fit.
