3.5 Backup Battery
An onboard 3V lithium battery provides back-up BIOS setup values and the real-time clock (RTC).
When replacing, connect the battery as follows:
1. Remove the battery from the socket.
2.
Insert a new battery in place with respect to the positive and negative location.
WARNING
There is a danger of explosion if you replace the battery incorrectly.
Replace the battery with the same or equivalent type recommended by the
manufacturer.
Dispose of used batteries according to the manufacturer's instructions.
3.5.1 Operation and Preventative Maintenance
The operational battery voltage must be between 2.4 and 3.0 volts.
When the board is stored in its original package, replace the battery if it falls below 2.4 volts.
For preventive operational maintenance, verify the battery voltage after four years. After that,
check the safety voltage more often. Battery life expectancy depends upon board use.
