Direct Replacement CMOS Battery

The DBTLAP lithium cell is a direct replacement for the Acer TravelMate 290 motherboard. It restores BIOS settings and real-time clock function when the original battery fails. Installation suits technicians or owners comfortable opening the laptop chassis.

Questions about this item

Will the CMOS battery keep the BIOS settings on my TravelMate 290 when the main battery is removed?

Yes, this lithium CMOS battery supplies the RTC power rail so the BIOS clock and settings are retained while the main battery is out.

How can I confirm the new CMOS battery is working after I install it?

Power on the laptop, enter the BIOS setup, set the correct date and time, save and exit, then cold-boot again — the clock should still show the right time.

Does the package include anything besides the single CMOS battery?

The box contains only the 1 x CMOS battery; no tools, cables or main laptop battery are included.
