Assembly precautions:
Users only need to disassemble and assemble the new battery when installing it. Please do not disassemble and assemble it
without authorization in other cases. Please do not touch the waterproof rubber strip, waterproof fixing head, waterproof LED
lamp and waterproof key during the process of assembling the battery. After the installation of the battery, you must use an electric
screwdriver with a torque set to 4kgf to assemble the housing screws (if there is no electric screwdriver, please use a cross
screwdriver with suitable screws to assemble and lock to ensure that the upper cover and the lower cover are assembled tightly),
otherwise the air tightness after assembly will be affected
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.
