The CPU monitors the discharge degree of the battery. A warning is issued before the battery
condition becomes critical (about 2 weeks before). Once the warning message appears, the
battery should be replaced as soon as possible.
● Do not short-circuit or re-charge the battery! It can cause excessive heating and explosion.
● Do not disassemble the battery!
● Do not heat up the battery and not put into fire! Risk of explosion.
● Store the battery in a dry place.
● Replace the battery with supply voltage ON in order not to risk data being lost.
● Recycle exhausted batteries meeting the environmental standards.
The battery lifetime is the time, the battery can store data while the processor module is not
powered. As long as the processor module is powered, the battery will only be discharged by its
own leakage current.
To avoid a short battery discharge, the battery should always be inserted or
replaced while the process module is under power, then the battery is correctly
recognized and will not shortly discharged.
