Black lithium-ion cell rated at 15 V and 44 Wh

The battery uses a standard lithium-ion chemistry in a black housing that matches the original form factor. It slides into the existing bay and connects through the laptop's native connector without adapters or cable modifications, so installation follows the same steps as the factory unit.

Rated for 15 V output with 44 Wh capacity

Under normal workloads the cell delivers its rated voltage and energy without additional cooling requirements. Power draw matches the original specification, and the pack operates silently because it has no moving parts. The supplier provides a 12 month warranty period.
