What this battery replaces

The DBTLAP CMOS battery is a direct replacement for the original coin cell on the Lenovo IdeaPad U350 motherboard. It restores the real-time clock and BIOS settings when the existing cell no longer holds a charge. This part is intended for repair technicians or owners comfortable opening a laptop chassis.

Behaviour over time

The lithium chemistry delivers a stable voltage for the CMOS circuit across years of continuous standby power. It maintains the system clock and firmware configuration through daily shutdown cycles without rapid self-discharge. The cell is tested before shipping to confirm it meets the required voltage threshold.

Installation notes

Replacement requires disassembling the laptop to reach the motherboard socket, so basic hand tools and anti-static precautions are necessary. Polarity must be observed when inserting the new cell to avoid damaging the CMOS circuitry. The package contains the single battery only; no tools or adhesive are included.

Questions about this item

Does the CMOS battery draw any power or generate heat while the Lenovo IdeaPad U350 runs all day?

The lithium CMOS battery only powers the real-time clock when the laptop is off, so it produces no measurable heat and consumes no power during daily operation.

What connector or cable must the Lenovo IdeaPad U350 already have on its motherboard for this replacement to fit?

The board needs the standard two-pin CMOS header with the matching plug that this DBTLAP battery provides.

Will this CMOS battery work if the IdeaPad U350 still has its original main battery and charger installed?

Yes, the CMOS cell operates independently and keeps BIOS settings alive regardless of the main battery or charger condition.
