4. If a lithium battery is stored for a long time, capacity loss may occur. After a
lithium battery is stored for 12 months in the recommended storage
temperature, the irreversible capacity loss rate is 3%–10%. If customers
perform the discharge test according to the specications, they may fail to
pass the test if the storage capacity of the battery is not 100% of the rated
capacity.
