The lithium -ray battery is very low from discharge and can be stored for 3 years. It will be better in preservation under refrigerated conditions. Stocking lithium -ray batteries in low temperatures is a good way.

　　Lithium -ion batteries can be stored for more than half a year at 20 ° C. This is because its self -discharge rate is very low, and most of the capacity can be restored.

　　The self -discharge phenomenon of lithium batteries, if the battery voltage is stored for a long time below 3.6V, will cause the battery to discharge and destroy the internal structure of the battery and reduce the battery life. Therefore, the long -stored lithium battery should be replenished every 3 to 6 months, that is, the charging to the voltage is 3.8 ~ 3.9V (the best storage voltage of the lithium battery is about 3.85V) is appropriate, and it should not be fully fully fulfilled.

　　The application temperature range of lithium batteries is wide. It can still be used outside the winter outdoors in the north, but the capacity will be reduced a lot. If it returns to room temperature, the capacity can be restored.
