DBTLAP CMOS Battery for ASUS S551L

This DBTLAP lithium CMOS battery is a direct replacement for the ASUS S551L motherboard. It restores the real-time clock and BIOS settings when the original cell fails. The unit is new and tested before shipping to ensure reliable operation.

Build quality and connector implications

The battery uses a standard lithium cell designed for laptop motherboard installation. Its connector matches the ASUS S551L socket, allowing a straightforward swap without soldering. Replacing a faulty or cracked unit prevents CMOS checksum errors and date resets during daily use.

Upgrade context and when to replace

This part replaces a depleted or damaged CMOS battery that causes lost BIOS configuration or system time. The jump is worth it when the laptop shows startup warnings, fails to retain settings, or the original cell is physically cracked. It is not for users needing a main laptop power battery.
