Compatible CMOS Battery for Sony Vaio VGN-FS415E

This DBTLAP lithium cell is a direct replacement CMOS battery for the Sony Vaio VGN-FS415E laptop. It restores BIOS settings and real-time clock function when the original cell fails. The battery is new and tested before shipping. It is intended for motherboard firmware power, not main system power.

Motherboard Slot Installation Frees Main Battery

The coin cell installs into the CMOS holder on the motherboard, requiring only basic disassembly to reach the socket. Once fitted, it maintains firmware data without drawing from the main laptop battery. This separation keeps the primary pack dedicated to runtime. No soldering or additional adapters are needed for the swap.

Single Tested Cell Ships Ready to Fit

The package includes one lithium CMOS battery verified by the supplier before dispatch. No cables, brackets, drivers or configuration utilities accompany the cell. The sole component replaces a faulty or depleted unit immediately. Buyers needing a full laptop battery or charger kit will not find those items here.
