Samsung RV520 CMOS Replacement

This lithium CMOS battery replaces the original BIOS RTC cell in Samsung RV520 laptops. It restores the system clock and firmware settings when the old battery fails. The part is intended for motherboard-level repair, not for the main laptop power pack. Buyers who need a main rechargeable battery pack should look elsewhere.

Pre-Tested Single Unit

Each battery is tested by the supplier before dispatch so it arrives ready to install. The package contains only the single CMOS cell with no extra cables, brackets or software. Technicians who expect a multi-pack or installation toolkit will not find them here.

Lithium Coin-Cell Limits

The lithium chemistry provides long shelf life and stable voltage for real-time clock duties. It cannot be recharged and is not designed for high-drain applications. Systems that require a rechargeable CMOS solution or a different form factor will not accept this cell.

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

No, the lithium CMOS battery operates passively with no moving parts, producing no audible noise and negligible heat.
