What is the optimal storage voltage for lithium batteries? And how much charge do they typically have when they are shipped from the factory?
Answer: The optimal storage voltage for a single battery is between 3.70-3.90V, and it typically comes with 30-60% charge when shipped from the factory. -
Can the battery be stored for a long time after being fully charged?
Answer: The storage time with a full charge should not exceed 7 days. It is best to store the battery with a single voltage of 3.70-3.90V, which helps extend the battery life. If it is not used for a long time, it is recommended to perform a charge and discharge operation every 1-2 months.
