Install battery
Medtronic MiniMed designed the pump to only accept a NEW battery. As a safety measure, if you
install a battery that does not have full power, the “weak battery” or “failed batt test” alarm may
sound. If you receive a “weak battery” alarm, respond to the alarm and continue. The pump will still
operate normally, but with a decreased battery life. The pump uses one AAA alkaline battery.
1 Make sure all the following apply:
➠ Clear (ESC, ACT) any alarms and/or alerts before removing and replacing the battery
➠ Make sure the pump is at the HOME (idle) screen when you remove the battery.
➠ Do NOT remove the battery during a bolus or prime delivery.
2 Use the edge of a coin to remove the battery cap. Turn the cap in a counter-clockwise direction.
3 Remove the old battery and dispose of it per the
disposable requirements of your state or country. Put
the new battery in the pump with the negative (-) end
going in first. Check the label on the back of the pump
to make sure the battery is inserted correctly.
NOTE - Do not use batteries that have been in
cold storage (i.e., in the refrigerator or your car in
the winter).
4 Place the battery cap in the pump and tighten so the slot is
aligned horizontally with the pump as shown here:
Do NOT apply force when you turn the cap.
CAUTION: Do not use a rechargeable or carbon zinc battery in your pump. For best
results, a new AAA Energizer alkaline battery is recommended.
CAUTION: Do NOT over-tighten the battery cap.
You should not turn the cap more than
four half-turns. If you over-tighten the
cap, you may not be able to remove it
and you can damage your pump.
