PowerWarehouse 245RR laptop battery 11.1V 91Whr Dell XPS 9350 Precision M3800

Compatible replacement for Dell XPS 9350

This 6-cell lithium-ion battery replaces OEM part numbers 245RR, 7D1WJ, H76MV and Y758W. It is built for Dell XPS 9350 and Precision M3800 laptops that require an 11.1V power source. The pack delivers 91Whr of capacity for extended mobile use. It ships new from a US-based supplier.

Practical limits of a 6-cell lithium-ion pack

Capacity is fixed at 91Whr and voltage at 11.1V, so runtime cannot exceed the design envelope of the original chassis. The six-cell layout determines the physical footprint; it will not fit systems engineered for a different cell count or voltage. Degradation over charge cycles will gradually reduce usable runtime. No higher-capacity version exists within this form factor.

The deciding specification: 11.1V 91Whr 6-cell match

Verify that the service tag or original battery label lists 11.1V and 91Whr with a six-cell configuration. If the laptop originally shipped with a different voltage or watt-hour rating, this pack will not operate correctly. The OEM part numbers 245RR, 7D1WJ, H76MV and Y758W are the definitive compatibility keys. Buyers whose devices require a different electrical profile must source the matching specification.
