Exact Replacement for Portege R600-S4201

This DBTLAP CMOS battery is built as a direct replacement for the Toshiba Portege R600-S4201 laptop. It restores the real-time clock and BIOS settings when the original cell has depleted. The lithium chemistry matches the factory specification for reliable long-term operation.

Build Integration and Clearance

The coin-cell form factor slots into the existing motherboard holder without adapters or soldering. Installing it frees the system from date resets and BIOS checksum errors that prevent boot. No additional cables, brackets or configuration steps are required.

Upgrade from a Dead or Leaking Cell

This unit replaces a failed CR-series CMOS cell that no longer holds a charge or shows signs of leakage. The jump is worth it when the laptop loses time, forgets boot order or prompts for BIOS setup on every start. It is not for users replacing the main laptop battery pack.
