REPLACEMENT SCHEDULE FOR
MOTHERBOARD BATTERY _______________________________
The shelf life of a CR2032 battery is about 10 years. When the battery is in an AT computer motherboard
(EPOX and Gigabyte) and the power is on, or when the battery is in an ATX motherboard (DFI) and the
power supply is merely plugged in, there is no current drawn from the battery and so it's expected life for
this situation is 10 years.
In an AT motherboard that is off or ATX motherboard that is unplugged, current is drawn from the
battery. The expected life for this situation is 3 years. In a realistic situation, the AT motherboard is on and
the ATX motherboard is plugged in for part of that time, so a realistic life expectancy for the battery would
be more than 3 years.
iZ recommends that the first replacement date for the motherboard battery should be 2 years from build
date of unit. After the first replacement, the on-going replacement should be every 3 years after that.
The invoice date or the date code in the RADAR serial number should be used as an accurate record for
indicating the build date.
