Replacement CMOS Battery for Latitude 5590

The DBTLAP lithium cell is a direct replacement for the CMOS RTC BIOS battery used in the Dell Latitude 5590. It maintains the real-time clock and BIOS settings when the main power is removed. The part is supplied new and tested before shipping.

Suitable for owners fixing a dead CMOS cell.

This battery suits technicians or owners replacing a faulty, cracked or exhausted CMOS cell that causes date loss or BIOS errors. It is not a main laptop battery and cannot power the system during use. Buyers needing a primary power source should look elsewhere.
