DBTLAP CMOS Battery for Samsung NP900X3C

This lithium CMOS battery replaces the BIOS RTC cell on Samsung NP900X3C laptop motherboards. It restores system time and firmware settings when the original cell fails. The unit is tested before shipping to confirm reliable operation.

Single replacement cell in the package

The box contains one CMOS battery only, with no additional cables, brackets or software. Installation simply swaps the old coin cell for this new unit on the motherboard. No driver installation or configuration utility is required.

Lithium coin-cell chemistry limits

Lithium CMOS cells provide long service life but cannot be recharged and must be replaced once depleted. They operate within a narrow voltage window, so polarity must be observed during fitting. The battery is not a main power source and will not run the laptop itself.

Questions about this item

How often will the CMOS battery in the Samsung NP900X3C need to be replaced?

The lithium CMOS battery typically lasts several years before the system clock drifts or BIOS settings reset, signalling it is time for a new one.

What is the first limitation that appears when the laptop runs continuously on this battery?

The 900 mAh capacity means the real-time clock and CMOS memory are maintained only while the main battery or AC power is disconnected for extended periods.

Does the CMOS battery generate any noticeable heat or noise during all-day operation?

No, the lithium cell is passive and produces no audible noise or measurable heat while keeping the BIOS clock running.
