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. This lithium chloride layer prevents rapid self-discharge caused by continuous reaction between
lithium and thionyl chloride, but battery passivation may also lead to voltage delay when the batteries are put into operation, and
our devices may not work correctly in this situation.
As a result, please make sure to source batteries from reliable vendors, and it is suggested that if the storage period is more
than one month from the date of battery production, all the batteries should be activated. If encountering the situation of battery
passivation, users can activate the battery to eliminate the battery hysteresis.
ER14505 Battery Passivation
7.1 To determine whether a battery requires activation
Connect a new ER14505 battery to a resistor in parallel, and check the voltage of the circuit.
If the voltage is below 3.3V, it means the battery requires activation.
7.2 How to activate the battery
a. Connect a battery to a resistor in parallel
b. Keep the connection for 5~8 minutes
c. The voltage of the circuit should be ≧3.3, indicating successful activation.
