CMOS Battery for ASUS c90 Laptops

This lithium CMOS battery is a direct replacement for the RTC backup cell on ASUS c90 laptop motherboards. It maintains BIOS settings and the system clock when main power is removed. The unit is tested before shipping and arrives new in a single-piece package.

For Owners Needing a BIOS Battery Swap

This part suits anyone whose ASUS c90 loses CMOS data or shows clock errors after shutdown. It is not for users replacing the main laptop battery pack or repairing a different motherboard model.

Lithium Chemistry Determines Fit

The lithium cell chemistry matches the original specification required by the ASUS c90 motherboard circuitry. Using a different chemistry would prevent proper voltage retention and BIOS operation.

Questions about this item

Does this CMOS battery require any additional cables or connectors to install in my ASUS c90 laptop?

The DBTLAP CMOS battery is a direct replacement unit that plugs into the existing motherboard header on your ASUS c90. No extra cables, adapters or tools are included or needed.

Will this lithium CMOS battery work correctly if my ASUS c90 originally shipped with a different battery chemistry?

Yes, the lithium chemistry is the standard type for CMOS RTC backup on laptop motherboards and will maintain BIOS settings and the real-time clock just like the original cell.

How can I verify the new CMOS battery is functioning properly after I fit it in the ASUS c90?

Power on the laptop, enter the BIOS setup and confirm the date and time hold correctly after a full shutdown and restart. The BIOS should retain settings without reverting to defaults.
