Direct replacement battery

The Beisite MN79H is a new lithium-ion battery built for the XPS 13 Plus 9320 series, including the XPS9320-7523BLK-PUS and XPS9320-7585SLV-PUS models. It replaces part numbers MN79H, J7H5M, NXRKW and 31CP4/78/78. The black pack installs inside the chassis without adapters. Buyers who need a different voltage or form factor cannot use this unit.

11.55V lithium-ion constraint

The cell chemistry delivers a fixed 11.55V output that matches the original specification for the 9320 platform. Capacity is rated at 55Wh, which defines the total energy available per charge cycle. The battery has no selectable voltage modes and cannot be recalibrated to other laptop families. Users who require a higher voltage or a different connector layout must look elsewhere.

55Wh capacity envelope

At 55Wh the pack supplies the same energy budget as the factory unit, supporting typical mixed workloads on the 13-inch platform. Runtime scales with screen brightness, CPU load and background services; heavy sustained workloads will deplete the charge faster than light browsing. The battery does not extend beyond the original 55Wh limit, so users who need longer unplugged time per session cannot achieve it with this replacement.

Questions about this item

Should I pick the 55Wh or a different capacity for my XPS 13 Plus 9320?

This battery is only offered at 55Wh, matching the original specification for the XPS 13 Plus 9320 series.

What runtime can I expect from the 55Wh rating once installed?

The 55Wh capacity restores the factory runtime for the XPS 13 Plus 9320; actual hours depend on your workload, screen brightness and power settings.

Does the 11.55V voltage limit compatibility to certain XPS 9320 sub-models?

The 11.55V rating matches the original part numbers MN79H, J7H5M, NXRKW and 31CP4/78/78, so it fits every listed XPS 9320 variant.
