DBTLAP CMOS Battery for ASUS UL80V

This DBTLAP lithium CMOS battery is designed for the ASUS UL80V laptop motherboard. It maintains BIOS settings and the real-time clock when the main power is disconnected. The part arrives new and tested, ready for direct replacement of a depleted or faulty unit. It is not a main laptop battery and will not power the system for portable use.

Sustained real-time clock retention under

The lithium cell delivers a steady low-voltage supply to the motherboard RTC circuit over extended periods without mains power. It prevents BIOS configuration loss and clock drift during long storage or travel intervals. The component is verified before shipping to confirm reliable voltage output. No recharge cycles are required during its service life.

Direct replacement for the original ASUS UL80V

This unit replaces the factory-fitted coin cell when it no longer holds charge, restoring persistent BIOS memory and accurate timekeeping. The upgrade is worthwhile when the laptop shows checksum errors, date resets or failure to retain boot order after shutdown. Builders needing a main power pack or a different form factor should select an alternative product.

Questions about this item

Does the DBTLAP CMOS battery generate any heat or noise while powering the ASUS UL80V motherboard continuously?

No, a lithium CMOS battery has no moving parts and draws only micro-amps, so it runs silently and without measurable heat.

What must I already have inside the ASUS UL80V for this replacement to fit and function?

You need the original two-pin CMOS header on the motherboard; the battery plugs directly into that connector.

Will this DBTLAP cell keep BIOS settings on an older ASUS UL80V that has been in storage for years?

Yes, the fresh lithium cell restores the RTC circuit and holds CMOS data once the laptop is reassembled and powered on.
