Compatible Dell Latitude D620 CMOS Battery

This lithium CMOS battery is designed for the Dell Latitude D620 motherboard. It replaces a faulty or depleted BIOS RTC cell that causes lost settings and clock errors. The part is new and tested before shipping. It is not a main laptop battery and will not power the system during use.

BIOS RTC Replacement For Motherboard

The single specification that decides fit is compatibility with the Dell Latitude D620 motherboard. This cell restores CMOS memory and real-time clock function when the original battery fails. Buyers who need a main rechargeable laptop battery cannot use this part.

Low-Power Lithium Cell Operation

The lithium chemistry provides stable voltage for CMOS memory with negligible current draw. Normal operation produces no audible noise and no measurable heat. Power consumption is far below one watt and does not affect system thermals or battery life.
