Lenovo IdeaPad U350 2963 CMOS Battery

This DBTLAP lithium CMOS battery replaces the BIOS RTC cell on Lenovo IdeaPad U350 2963 laptops. It is a new component tested before shipping and intended for motherboard use, not the main laptop battery. The package includes one battery.

Who this suits and who should look elsewhere

Suitable for owners of a Lenovo IdeaPad U350 2963 experiencing CMOS checksum errors or lost BIOS settings. Not for users needing a main system battery, a different laptop model, or a rechargeable lithium-ion power pack.

Installation ease and common issues

Installation requires opening the laptop chassis to access the motherboard socket. Polarity must match the original cell; incorrect orientation prevents the system from retaining BIOS data. Static precautions are advised when handling the motherboard.
