DBTLAP CMOS Battery for Samsung R520

This DBTLAP CMOS battery is a lithium coin cell designed to replace the BIOS RTC battery on Samsung R520 laptop motherboards. It is a direct replacement part for a faulty, cracked or depleted original cell. The unit is tested before shipping and supplied as a single battery. It is not a main laptop power battery.

Lithium coin cell practical limits

A lithium CMOS cell provides the low current needed to keep the real-time clock and firmware settings alive while the laptop is off. Its voltage will gradually decline over several years until the system loses date, time or boot configuration. The battery is not rechargeable and cannot be used to power any other component.

Check motherboard compatibility before ordering

Verify that your laptop is the Samsung R520 model and that the existing CMOS battery is a removable coin cell with the same form factor. Some revisions may use a soldered cell or a different connector, which this part will not fit. Ensure you are comfortable opening the chassis to reach the motherboard.
