Compatible CMOS Battery for Samsung Q45

This lithium CMOS battery is designed as a direct replacement for the Samsung Q45 laptop motherboard. It restores the system clock and BIOS settings when the original cell fails. The part is supplied new and tested before shipping to ensure reliable operation. It is intended for laptop motherboards, not main laptop power batteries.

Straightforward Motherboard Installation

Replacing the CMOS cell requires opening the laptop chassis to access the motherboard socket. The battery fits the existing connector without soldering or adapters. Common issues include forgetting to disconnect the main battery first or damaging the delicate connector during removal. Ensure the polarity matches the socket orientation before seating the new cell.

Verify Laptop Model Before Ordering

Confirm that your device is the Samsung Q45 before purchasing, as connector types and voltages differ between models. This battery is not suitable for main system power or for other laptop series. Check the existing motherboard battery markings to match the lithium chemistry and form factor. No additional tools or cables are included in the package.
