Information About Battery Passivation - netvox R718N1 User Manual

Note:
Please do not disassemble the device unless it is required to replace the batteries.
Do not touch the waterproof gasket, LED indicator light, function keys when replacing the batteries. Please use suitable screwdriver to
tighten the screws (if using an electric screwdriver, it is recommended to set the torque as 4kgf) to ensure the device is impermeable.

8. 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 the batteries should be produced within the last three
months.
If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis.
*To determine whether a battery requires activation
Connect a new ER14505 battery to a 68ohm resistor in parallel, and check the voltage of the circuit.
If the voltage is below 3.3V, it means the battery requires activation.
*How to activate the battery
1) Connect a battery to a 68ohm resistor in parallel
2) Keep the connection for 6~8 minutes
3) The voltage of the circuit should be ≧3.3V
