CMOS Battery for Dell Inspiron 1720

This lithium CMOS battery replaces the onboard RTC cell that keeps BIOS settings and the system clock alive when the laptop is off. It is intended for owners of the Inspiron 1720 who lose date, time or boot configuration after a shutdown. The part is a direct replacement for the original coin cell on the motherboard.

Replaces a depleted original cell

Swap this battery when the machine forgets the clock, shows CMOS checksum errors or refuses to retain BIOS changes. The upgrade is worth it if the laptop otherwise runs well but fails to hold settings between power cycles. No other components are affected by this change.

Verify the exact model before ordering

Confirm the service tag or chassis label reads Inspiron 1720; other Dell models use different coin-cell sizes or connector layouts. Ensure you are comfortable opening the case to reach the motherboard socket. The package contains one tested battery only.
