Compatible Replacement Battery

The Beisite NP50BAT-4-73 is a new lithium-ion battery built for Clevo NP50SNC chassis and the many laptops based on it. It fits Medion Erazer Defender P40, XMG Focus 15 and 17 E23 models, Schenker Media and XMG Focus variants, System76 Adder WS, Hasee TX8R7 TX9R7 TX9R9 and Colorfly X15AT X17AT machines. Buyers with other Clevo or Tongfang platforms not listed should verify the part number before ordering.

Direct Drop-In Installation

The pack replaces part numbers 6-87-NP5SS-71M00 and 6-87-NP5SS-73A00 without adapters or cable changes. It slots into the existing battery bay and connects to the motherboard header, so the laptop charges and reports capacity through the standard firmware. No BIOS update or external charger is required, freeing the technician from sourcing proprietary connectors or rewiring the power path.

73 Wh Capacity and Limits

Rated at 15.4 V and 4600 mAh, the cell delivers 73 Wh for typical office or light gaming sessions away from mains power. Runtime scales with screen brightness, CPU load and discrete GPU use; heavy workloads will drain the pack faster than the rated figure suggests. The battery does not increase the original design capacity, so users needing significantly longer unplugged time must consider a larger-capacity alternative or an external power bank.

Questions about this item

How long will the 73Wh capacity last under sustained load before the battery hits its voltage floor?

The 73Wh rating delivers 4600mAh at 15.4V; actual runtime depends on the laptop's power draw, so a high-load session will deplete it faster than light use.

Does the lithium-ion pack run hot or loud during all-day operation?

The battery itself has no fan and generates only normal cell warmth; any heat or noise comes from the laptop's cooling system, not the pack.

Which original part numbers must match for this NP50BAT-4-73 to work in my machine?

It replaces part numbers 6-87-NP5SS-71M00 and 6-87-NP5SS-73A00; verify one of those codes on your old battery before fitting.
