Replacement CMOS Battery for Samsung RV520

This lithium coin cell replaces the BIOS real-time-clock battery on Samsung RV520 laptop motherboards. It restores date, time and firmware settings that are lost when the original cell is exhausted. The part is supplied new and tested before shipping.

Single Battery Included

The package contains one CMOS battery only; no tools, cables or additional hardware are provided. Installers must open the laptop chassis and swap the cell themselves using their own equipment.

Lithium Coin-Cell Limitations

The lithium chemistry delivers the low self-discharge required for multi-year timekeeping but cannot be recharged by the motherboard. When the voltage eventually drops below the CMOS threshold the system will again lose BIOS settings until the cell is replaced.

Highlights

  • Compatible with Samsung RV520 motherboards
  • Lithium chemistry provides stable BIOS power

  • Pre-tested for reliable operation

Questions about this item

How often will the CMOS battery need replacement in the Samsung RV520?

The lithium CMOS battery typically lasts several years before the system clock or BIOS settings start to drift, signalling it is time for a fresh unit.

What is the first limit reached when the laptop runs continuously on this battery?

The battery only powers the real-time clock and CMOS memory, so its capacity is never stressed by sustained system use.

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

No, the lithium cell produces no audible noise and negligible heat while maintaining the BIOS clock and settings.
