Compatible CMOS Battery for ASUS K56CB

This DBTLAP lithium CMOS battery replaces the BIOS RTC cell on ASUS K56CB laptop motherboards. It restores system time and firmware settings when the original coin cell is exhausted. The unit is tested before shipping and arrives new. Buyers needing a main laptop power pack should look elsewhere.

Thermals and Power Draw in Normal Use

The lithium chemistry delivers a steady low-voltage supply with negligible heat output. Power consumption is minimal and produces no audible noise during operation. No active cooling or additional power circuitry is required on the motherboard.

Installation Fit and System Impact

The battery slots directly into the existing CMOS holder on the K56CB board, freeing the system from date resets and BIOS checksum errors. No cables, adapters or firmware updates are needed. Builders working on unrelated laptop models or desktop boards cannot use this part.

Highlights

  • Compatible with ASUS K56CB motherboards

Questions about this item

How do I install this CMOS battery in my ASUS K56CB and which step do people often get wrong?

Open the laptop case, locate the coin-cell socket on the motherboard, remove the old cell and press the new DBTLAP lithium unit in with the positive side facing up; the common mistake is inserting it upside-down.

What maintenance or replacement will this CMOS battery need later?

The lithium CMOS cell typically lasts several years; when the system clock starts losing time or BIOS settings reset, replace it with another identical coin cell.

What limit shows up first under sustained use?

The battery’s finite lithium capacity is the limiting factor; once its charge is depleted after years of maintaining the RTC, the clock will drift and settings will clear.
