5.3 Example for MinTime/MaxTime logic Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange=0.1V MaxTime MaxTime sleeping (MinTime) sleeping (MinTime) Wakes up and collect data Wakes up and collect data Wake up and collect data REPORTS 3.6V REPORTS 3.6V REPORTS 3.6V... - Page 10 Notes: 1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data. 2) The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange value, the device reports according to MinTime interval.

Page 12: Information About Battery Passivation
7. Information about Battery Passivation Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high. -
