Compatible CMOS Battery for Samsung NP530U3B

This DBTLAP lithium CMOS battery replaces the BIOS RTC cell on Samsung NP530U3B laptop motherboards. It is a new component tested before shipping to restore system time and firmware settings. The package includes one battery ready for installation.

For owners of the Samsung NP530U3B

This part suits anyone whose NP530U3B loses the date, time or BIOS configuration after power loss. It is not for users who need a main laptop battery to run the system, nor for any other laptop model.

Lithium coin cell restores BIOS settings

The lithium chemistry provides the steady low current that keeps the real-time clock and CMOS memory alive while the laptop is off. Replacing a depleted cell with this unit returns the NP530U3B to normal start-up behaviour.
