Battery passivation

Some types of Connect Sensor lithium batteries experience passivation when the battery is not used
for a period of time. If you are using external power, and never use the battery, the battery will
passivize within the Connect Sensor.
Battery passivation can cause the battery to report a low battery percentage for a time after initial
installation. As the device uses the battery, the passivation is removed and the battery percentage
increases to a maximum of 90 - 100% (depending on the temperature). The passivation removal
process could take a week or more, if the number of times Digi Connect Sensor+ wakes to send
reports to Remote Manager is once per day or less.
Note Passivation may never be removed if the device sends reports to Remote Manager too
infrequently.

Replace a battery

Before replacing the battery, review the
necessary tools and equipment. For more information about battery life, see
1. Open the enclosure.
2. Disconnect the battery.
a. Press in the tab at the top of the battery wire connector.
b. Pull up on the connector.
3. Remove the existing battery.
4. Place the new battery in the battery holder and connect the wiring to the battery port. Make
sure the battery and its wiring are properly placed.
5. Press the Wake button and wait for the battery LED to slowly blink blue five times and then
remain off.
6. Reassemble the device.

CSENSE Continuous Monitoring power source

For some customers, the scheduling paradigm of the standard Connect Sensor offering is inadequate.
Digi offers an alternate firmware image that trades alarm reactivity for power consumption. The
CSENSE Continuous Monitoring firmware image can be downloaded and installed on a Connect
Sensor.
