Battery Life Advisory
All modules in the MVI series use a rechargeable Lithium Vanadium Pentoxide battery to
backup the 512K SRAM memory, real-time clock, and CMOS. The battery should last for
the life of the module.
The module must be powered for approximately twenty hours before it becomes fully
charged. After it is fully charged, the battery provides backup power for the CMOS setup
and configuration data, the real-time clock, and the 512K SRAM memory for
approximately 21 days.
Before you remove a module from its power source, ensure that the battery within the
module is fully charged. A fully charged battery will hold the BIOS settings (after being
removed from its power source) for a limited number of days (15 for the PC56). When
the battery is fully discharged, the module will revert to the default BIOS settings.
Note: The battery is not user replaceable.
