Lithium ion battery
Also known as a secondary Lithium battery. Under the 20 ℃ can be stored for more than six months, it is because of its low self-discharge rate, and most of capacity can be restored.
Self-discharging phenomenon of Lithium Battery exists. If the battery voltage is under 3.6v for a long time, it will lead to over-discharge of the battery and damage the internal structure of the battery, thus reducing the battery life. Therefore, the long-stored lithium battery should be recharged every 3~6 months, that is, the charging voltage is 3.8-3.9v (the best storage voltage of lithium battery is about 3.85v), and it is appropriate to keep it at a discharge depth of 40-60%, rather than full. Batteries are to be kept at 4 ℃ ~ 35 ℃ or moisture-proof packaging in dry environment. Stay away from heat sources and avoid exposure to direct sunlight
