Can I put the battery in the refrigerator?
Someone suggested that I put the rechargeable battery in the freezer in the refrigerator. This is indeed a good idea.
Lithium-ion batteries need to be fully charged and stored. It can be stored for more than half a year at 20 ° C. It can be seen that the lithium ion battery is suitable for storage at low temperatures. Lithium-ion battery has self-discharge phenomenon. Long-term storage will cause over-discharge of the battery to damage the internal structure of the battery and reduce battery life. Therefore, long-term storage of lithium-ion power batteries should be recharged every 3 to 6 months, that is, charging to a voltage of 3.8 to 3.9 volts (the optimal storage voltage of a lithium battery is about 3.85 volts).
