Compatible CMOS battery for Aspire 9800

This DBTLAP lithium CMOS battery replaces the RTC backup cell on Acer Aspire 9800 laptop motherboards. It keeps the system clock and BIOS settings alive when the main power is removed. The unit is new and tested before shipping.

Replaces a dead or leaking original cell

Swap this battery when the laptop loses time, forgets BIOS configuration or shows CMOS checksum errors at boot. The change is worth it if the machine otherwise runs well and you want to avoid a motherboard repair.

Check motherboard access

Verify that your Aspire 9800 uses a removable coin-cell holder rather than a soldered cell. Confirm the connector layout matches the original so the replacement fits without modification.

Questions about this item

Does the DBTLAP CMOS battery use a connector that fits the Acer Aspire 9800 motherboard header?

The DBTLAP CMOS battery is a direct replacement for the Acer Aspire 9800 motherboard and ships with the correct connector for that model.

What is the correct polarity orientation when inserting the CMOS battery into the Acer Aspire 9800?

Match the red wire to the positive pin and the black wire to the negative pin on the motherboard header; reversing them will prevent the BIOS from retaining settings.

How often should the lithium CMOS battery in the Acer Aspire 9800 be replaced?

A lithium CMOS battery typically lasts three to five years; replace it when the system clock drifts or BIOS settings reset after power loss.
