Warnings
1. This battery cannot charge.
2. This battery can not replace alkaline batteries.
3.Although our battery has a lifespan of 10 years (under special storage conditions), we advise customers not to store batteries for a long time due to passivation characteristic. We strongly recommend the customer to use the battery within 3 months to achieve optimal performance.

What to do if your battery does not work when connected to the device?
1. Test OCV (Open Circuit Voltage). You can use the multimeter to test the voltage. The standard voltage should not be less than 3.6V, if your battery is less than 3.6V, please contact us.
2. Charging voltage test. The charging voltage should be about 3.2V, if your charging voltage is more than 3.2V, the battery is in good condition. Due to the passivation characteristic of lithium thionyl chloride, your charging voltage may not reach 3.2V immediately. You can connect the battery with a resistor and activate it with a multimeter. When the battery charging voltage reaches 3.2V, activation is successful and the battery can be used.
3. If the battery does not turn on or is still unusable after activation, please contact us.
