Targeted replacement

This DBTLAP CMOS battery is a direct replacement for the Samsung NP900X4C and 900X4C laptop models. It restores the real-time clock and BIOS settings when the original cell fails. The lithium cell is tested before shipping to ensure reliable operation. It is intended for laptop motherboards, not the main system battery.

Motherboard installation

The battery fits onto the motherboard to maintain CMOS memory when the laptop is powered off. No additional cables or chargers are required for installation. Replacing a faulty unit frees the system from date resets and BIOS errors. The package includes a single battery for a straightforward swap.

Low power operation

As a standard lithium CMOS cell, it draws negligible current during normal operation. The component produces no audible noise and generates no measurable heat. Power consumption is minimal, limited to maintaining the real-time clock and BIOS configuration. It operates passively inside the laptop chassis.
