DBTLAP CMOS Battery for ASUS Eee PC MK90H

This replacement CMOS battery restores BIOS clock and configuration retention on compatible ASUS Eee PC MK90H laptops. It is intended for technicians or owners repairing a motherboard that loses date, time or hardware settings after power loss. The lithium cell arrives new and tested before shipping.

Sustained reliability on the motherboard

The lithium chemistry delivers the steady, low-current output required for real-time clock and CMOS memory circuits over long periods. Unlike a main laptop battery, this cell is not subjected to high-drain cycles, so its voltage remains stable throughout its service life. Each unit is verified before dispatch to confirm it meets the board’s standby power needs.

Check motherboard compatibility before ordering

Confirm that your laptop uses the exact MK90H motherboard variant, as CMOS battery connectors and form factors differ between models. This part is a CMOS BIOS RTC battery only and will not power the main system or replace a depleted primary laptop battery. Buyers needing a main power pack or a different connector type should source the correct alternative.

Questions about this item

Does the CMOS battery generate any noise or heat while the ASUS Eee PC MK90H runs all day?

No, the lithium CMOS battery is a passive component that sits on the motherboard and produces no audible noise or noticeable heat during continuous operation.

What else must I already own for this DBTLAP CMOS battery to work in my ASUS Eee PC MK90H?

You need the laptop itself with an accessible motherboard socket and a small screwdriver to open the case and swap the old cell.

Will this replacement CMOS battery work alongside the original ASUS motherboard and other older components in the Eee PC MK90H?

Yes, it is a direct lithium replacement for the factory BIOS RTC cell, so it fits the existing socket and maintains clock and CMOS settings with the original hardware.
