What this battery replaces

The DBTLAP CMOS battery is a direct replacement for the ASUS X501A-XX036V motherboard coin cell. It is intended for laptop owners who need to restore BIOS settings and system clock accuracy after the original cell has failed.

Critical specification — lithium chemistry

This cell uses lithium chemistry to provide the stable 3 V supply that the real-time clock and CMOS memory require. Builders who need a different voltage or a rechargeable type should look elsewhere because this unit is a primary lithium coin cell only.

Installation notes

The battery ships new and pre-tested, ready to be fitted into the motherboard holder without soldering. The only common issue is inserting the cell with reversed polarity, which prevents the system from retaining BIOS data.

Questions about this item

What does the 3 V lithium cell actually power once it is installed in the laptop?

It keeps the real-time clock running and preserves BIOS settings whenever the main battery is removed or fully drained.

What connector standard does the 3 V cell use to attach to the motherboard?

The cell ships with a two-pin plug that matches the original CMOS header on the ASUS X501A-XX036V board.

Will the replacement cell fit the existing holder without modification?

The unit is built to the same physical dimensions as the factory battery, so it seats directly in the original holder.
