DBTLAP CMOS Battery for ACER TravelMate 6592G

Compatible CMOS battery for TravelMate 6592G

This DBTLAP lithium coin cell replaces the onboard BIOS RTC battery inside the ACER TravelMate 6592G notebook. It restores system time, date and firmware settings that are lost when the original cell is exhausted. The part is supplied new and tested before shipment. It is intended for motherboard-level replacement, not for the main laptop battery pack.

Practical limits of the lithium coin cell

The cell provides the low continuous current required by the real-time clock and CMOS memory only. It cannot power any other subsystem, charge external devices or serve as a primary energy source for the notebook. Service life depends on motherboard leakage current and ambient temperature; the battery will eventually require replacement again. No charging circuitry is present on the cell itself.

Lithium chemistry defines the correct part

The replacement uses a lithium chemistry that matches the voltage and form factor expected by the TravelMate 6592G motherboard. Installing a different chemistry or voltage would prevent the BIOS from retaining settings. Buyers whose notebook uses a different CMOS cell type or who need a main power battery should select a different product.
