Three-Cell Lithium-Ion Build

The battery uses a three-cell lithium-ion pack rated at 11.55V. It slots directly into the internal battery bay without adapters or cable modifications. No external charger or docking station is required for daily operation.

51Wh Capacity Decides Runtime

The 51 watt-hour rating determines how long the laptop runs on a single charge under typical workloads. If your workflow demands significantly longer unplugged time, this capacity may fall short.
