DBTLAP CMOS Battery for Dell Latitude E6400 XFR

This lithium CMOS battery replaces the BIOS RTC cell on a Dell Latitude E6400 XFR motherboard. It is a new component tested before shipping and intended for technicians or owners who need to restore system time and BIOS settings after the original cell fails.

Capacity and headroom for the Latitude E6400 XFR

The battery supplies the low current required to keep the real-time clock and CMOS memory active when the laptop is unplugged. It comfortably handles that standby load for its rated service life and runs out only when the lithium chemistry is exhausted after extended use.

Thermals noise and power draw in normal use

The cell operates passively with no fan or moving parts, so it produces no audible noise. Power draw is limited to the microampere leakage needed to maintain the RTC and CMOS, adding negligible heat inside the chassis.
