ProSoft Technology MVI46-MCM - Manual (Page 4)

Battery Life Advisory
The MVI46, MVI56, MVI56E, MVI69, and MVI71 modules use a rechargeable Lithium Vanadium Pentoxide battery to
backup the 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 the battery becomes fully charged. After it is fully charged, the battery
provides backup power for the CMOS setup and the real-time clock for approximately 21 days. When the battery is
fully discharged, the module will revert to the default BIOS and clock settings.
Note: The battery is not user replaceable.
