Battery Life Advisory
MVI46, MVI56, MVI69 and MVI71 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.
When the battery is fully discharged, the module will revert to the default BIOS settings.
Note: The battery is not user replaceable.
