What if your battery doesn't work when connected to the device?
1. Test the OCV(Open Circuit Voltage). You can use the multi-meter to test the voltage. Standard voltage should be no less than 3.6V. If your battery is lower than 3.6V, please tell us.
2. Test loading voltage. The loading voltage should be around 3.2V. If your loading voltage is higher than 3.2V, the battery is in good condition. Due to the passivation characteristic of lithium thionyl chloride, your loading voltage may not reach 3.2V immediately. You can connect the battery with a resistor and activate it with a multimeter. When the loading voltage of the battery reaches 3.2V, then the activation is successful and the battery can be used.
3. If the battery fails to activate or is still unusable after activation, please tell us for help.
