What this battery replaces

This 91Wh lithium-ion pack replaces Dell part numbers 245RR, 0H76MY, H76MV, 07D1WJ, 7D1WJ, Y758W, T0TRM and 31CP8/57/77-2. It is built for XPS 15 9530 and 9535 models plus the Precision M3800 series. The black casing matches the original colour.

Voltage and chemistry limits

The cell chemistry is lithium-ion at 11.1V nominal, so the pack only works in laptops designed for that exact voltage. Using it in a system expecting a different voltage will prevent boot or trigger a safety shutdown. No other chemistry or voltage is supported.

Capacity and runtime headroom

At 91Wh the battery delivers a full day of typical office work on a healthy XPS 15 9530 or Precision M3800. Heavy workloads such as sustained rendering or gaming will drain it faster, and the pack cannot extend runtime beyond its rated watt-hours. Buyers needing longer unplugged time must carry a second pack or use external power.

Questions about this item

Is the 91Wh 245RR the only capacity offered for my XPS 15 9530?

The listing shows a single 91Wh 245RR unit; no other capacities or models are presented for the XPS 15 9530, 9535 or Precision M3800.

What runtime can I expect from the 91Wh 11.1V pack in daily use?

A 91Wh lithium-ion cell at 11.1V typically powers a 15-inch workstation for several hours of mixed workloads before needing a recharge.

Does the 245RR connect through the standard Dell battery interface used by the Precision M3800?

Yes — the 245RR replaces part numbers 245RR, 0H76MY, H76MV, 07D1WJ, Y758W, T0TRM and 31CP8/57/77-2, matching the factory connector.
