DBTLAP CMOS Battery for Dell Inspiron 1720

This replacement CMOS battery restores BIOS settings and real-time clock function on Dell Inspiron 1720 laptops. It is a lithium coin cell intended for the motherboard, not the main laptop battery. The part suits owners whose system clock resets or who see BIOS checksum errors at boot.

Simple motherboard installation

The battery plugs directly into the existing motherboard connector, so no tools beyond a screwdriver for the chassis are needed. Common issues arise if the connector orientation is reversed or if the old battery residue corrodes the header pins. Ensure the laptop is fully powered down and the main battery removed before starting.

Lithium coin cell chemistry

The cell uses lithium chemistry to provide the stable 3 V supply the RTC circuit expects. It is a direct replacement for the original factory-fitted CMOS unit. Buyers needing a main power pack or a higher-capacity reserve cell should look elsewhere.
