Never allow the batteries to become short-circuited during handling.
CAUTION: handling batteries incorrectly or replacing with not-approved devices may present a risk of fire or explosion.
Batteries supplied with SBC-A80-eNUC are compliant to requirements of European Directive 2006/66/EC regarding batteries and accumulators. When putting out
of order SBC-A80-eNUC, remove the batteries from the board in order to collect and dispose them according to the requirement of the same European Directive

The battery is not rechargeable, and can be connected to the board using dedicated connector CN5 which is a 2-pin
p1.27 mm type MOLEX p/n 53398-0271 or equivalent, with pinout shown in the table on the left.
Mating connector: MOLEX 51021-0200 receptacle with MOLEX 50079-8000 female crimp terminals.
In case of exhaustion, the battery should only be replaced with devices of the same type. Always check the orientation before
inserting and make sure that they are aligned correctly and are not damaged or leaking.
