Dell Chromebook 13 3380 Battery Cable TN75D

This genuine Dell OEM cable connects the system battery to the motherboard inside the Chromebook 13 3380. It is the exact replacement part identified by Dell part number TN75D. The component arrives new and matches the unit pictured by the supplier.

Build Quality and Connector Fit

The cable uses the original Keystone13 Chrome BTY CABLE design with part marking 450.0A402.0001 for precise alignment. Its connectors seat directly into the existing battery and motherboard headers without adapters. Routing follows the factory path so the assembly closes cleanly.

What This Replaces and When to Fit It

This part replaces a damaged or worn battery-to-board cable that prevents charging or causes intermittent power loss. The jump is worth it when diagnostics confirm the cable as the failure point rather than the battery or charging circuit. It is not for buyers who need a battery pack, a charger or a motherboard.
