DBTLAP CMOS Battery for TravelMate 8573T

This is a replacement CMOS RTC battery designed for the Acer TravelMate 8573T laptop motherboard. It supplies the low-voltage power that keeps BIOS settings and the real-time clock running when the main battery is removed. The unit is a standard lithium coin cell supplied new and tested before shipping. It is intended for repair technicians or owners performing board-level maintenance.

Compatibility check before ordering

Verify that the target machine is the exact TravelMate 8573T model before purchase. Confirm the motherboard uses a removable coin-cell CMOS battery rather than a soldered or integrated solution. Check the existing cell voltage and connector style against the replacement to ensure a direct fit. This part is not a main laptop battery and will not power the system during normal operation.

Thermals noise and power draw

As a passive lithium coin cell the battery generates no heat and produces no audible noise during operation. Power draw is negligible, limited to the microampere leakage required to maintain the real-time clock and CMOS memory. No active cooling or additional power-supply capacity is needed for this component.
