For some batteries, such as lead acid batteries, it is necessary to retain a full charge before going into storage for long periods of time. Other batteries can be discharged fully before being placed into storage.
Lithium-ion batteries should not be fully charged during storage. In reality self-discharge is a phenomenon that exists in lithium-ion batteries.If the lithium ion battery storage voltage is stored below 3.6V for a long time, it can lead to over-discharge of the battery, which damages the internal structure of the battery and reduces its lifespan.
For nickel-based batteries, such as nickel cadmium and nickel metal hydride, they can be stored in both a discharged state and a charged state. However, if stored with a charge, both batteries will experience a high self-discharge rate of 10-15% during the first 24 hours.
Special battery storage considerations are required to prevent batteries from becoming overcharged and degrading in equipment. Different battery chemistries have specific requirements to reduce the discharge rate and maintain optimal charge capacity.
Lithium batteries should be stored in climatically controlled warehousing for optimum storage and battery performance. Within the first 24 hours at normal room temperatures, lithium batteries with lithium-ion chemistries will experience a discharge rate of 5 percent.
Some batteries, such as those that can be discharged fully, can be stored with varying states of charge. However, batteries like lead acid must be kept at a full charge before going into storage for extended periods to prevent age-related capacity loss. The reasons for this requirement are related to the specific chemistry of these batteries.
