DBTLAP CMOS Battery for Dell Latitude 6520

This DBTLAP lithium CMOS battery replaces the BIOS RTC cell on a Dell Latitude 6520 motherboard. It is a new component tested before shipping and packaged as a single unit. The part restores system time and firmware settings when the original cell fails. It is not a main laptop power battery.

For Latitude 6520 owners with a dead BIOS battery

This suits anyone whose Latitude 6520 loses the date, time or BIOS configuration after a shutdown. It is not for users who need a replacement for the main rechargeable battery that powers the portable computer. Buyers looking for a primary power source should look at something else.

Lithium coin cell restores BIOS settings

The lithium chemistry provides the steady low current required to keep the real-time clock and CMOS memory alive while the notebook is off. Swapping the old cell with this tested unit re-enables persistent firmware settings and correct boot-time behaviour.
