I don't need to buy new lithium batteries. How long can I keep it?

Lithium batteries should be stored in a cool and dry place after they are not used for a long time. Charge it every 3 or 5 months, so as to keep the capacity from "shrinking".

Lithium batteries can be stored for a long time.

Lithium batteries have a bad characteristic-self-discharge, which is related to voltage (charging amount, that is, charging saturation state). Therefore, lithium batteries stored for a long time should be charged with a certain amount of electricity, and the capacity of lithium batteries will be lost during storage (lithium batteries are effective). The charging amount and storage temperature of lithium battery will affect the capacity of lithium battery. The following are the remaining capacities of lithium batteries after one year's storage at different temperatures and full state:

Storage temperature -40% charging state-100% charging state

Storage temperature -40% charging state-100% charging state

0 degrees -98%-94%.

25 degrees -96%-80%.

40 degrees -85%-65%.

60 degrees -75%-60%.
