Direct Replacement for Dell Inspiron 17R 5720

This CMOS RTC battery is a direct replacement for the Dell Inspiron 17R 5720 laptop. It restores the real-time clock and BIOS settings when the original cell fails. The part is intended for repair technicians or owners comfortable opening the chassis. It is not a main power battery and will not run the laptop.

Lithium Coin Cell with Pre-Tested Reliability

The lithium coin cell arrives new and pre-tested by the supplier before shipping. It mounts directly onto the motherboard using the existing solder tabs or connector. No extra cables or adapters are required for installation. Buyers who need a main laptop battery or a higher-capacity CMOS cell will not be served by this part.

Limited to CMOS Time and BIOS Retention

The battery only maintains the system clock and CMOS memory while the laptop is unplugged. It does not power any other subsystem or extend runtime. If the motherboard has damaged charging circuitry, the new cell will not solve the issue. Users seeking longer BIOS retention during extended storage cannot increase capacity with this component.
