Lithium-ion batteries have many advantages, including high voltage, large compacity, high energy density, and long lifespan, to name just a few. These are popular batteries for smartphones, electric cars, and home energy storage systems.
Despite the benefits of lithium-ion batteries I mentioned above, you should be aware that Lithium-ion batteries sometime could be dangerous because they can overheat, catch fire, or explode. Thus, it''s necessary to get better knowledge about the different types of lithium-ion batteries, what they are made of, how they work, and most importantly, understanding the best way to store lithium-ion batteries when not in use, to minimize the risk of lithium battery fire or explosion.
In this guide, I''ll explain everything you need to know about storing lithium-ion batteries, for example:● Where is the best place to store a lithium-ion battery?● Is it better to store lithium batteries charged or uncharged?● At what temperature should a lithium-ion battery be stored?
The ideal temperature for storing the lithium battery is between 5 °C and 20 °C (41 °F and 68 °F). To be more specific, you can check the labels of your battery type and set the proper temperature before storing them. And there''s one thing to remember, Li-ion battery degradation is mainly caused by chemical exothermic reactions, and the high temperature will accelerate the degradation of lithium-ion batteries. So, keep your lithium battery at low or room temperature to slow down the decomposition process of the battery.
For best results, keep the lithium-ion batteries at a relative humidity of about 50%. If the lithium or lithium-ion battery is exposed to n high-moisture environments, it will lead to the reduced performance and reduced lifespan of lithium-ion batteries. If possible, refrigerate the battery in a dry environment to extend the battery life.
When not using your lithium-ion batteries, store them at around 40% -50% state of charge (SoC). And keep in mind that lithium-ion batteries should never be stored fully charged or completely discharged. On the one hand, lithium-ion batteries will gradually self-discharge, and they will lose large amounts of their usable life if they''re fully charged all the time. On the other hand, storing lithium-ion batteries fully discharged will be harmful to the battery cell.
In the previous paragraphs, you''ve learned the three main factors that impact the battery''s health, which are temperature, state of charge, and humidity. The following parts are the general guidelines for you to properly store your lithium-ion batteries and maximize the lifetime of your lithium-ion battery.
1. Remove the battery from the device before storing it.2. Use plastic, electrical tape, or other insulating materials to protect the battery terminal.3. Keep the battery in a fireproof container.4. Remove flammable, combustible materials, and liquids from the storing area.5. Handle lithium-ion batteries with caution and wash hands after handling them.6. Cover the discarded batteries with insulating paper to prevent explosion and fire.
1. Do not use damaged, swollen lithium-ion batteries.2. Do not expose the Li-ion batteries to excessive vibration.3. Do not store batteries in high or low temperatures.4. Do not place the Li-ion batteries in the microwave or high-voltage environment.5. Do not charge the lithium battery with inferior or other battery chargers.6. Do not put the lithium battery in water.
Yes. All batteries, including lithium-ion batteries and other types of batteries, will degrade over time even if you don''t use them. It is reported that a fully charged lithium-ion battery will reduce 20% of its capacity after a year of storage.
Lithium-ion batteries are famous for their poor cold-weather performance. If you store the battery at freezing temperatures, it will do harm to the battery cathode, making it separate from other parts of the battery. During winter, I recommend storing lithium-ion batteries at 50% state of charge in an environment above freezing.
The ideal place for storing batteries should be away from sunlight, heat, and humidity. You can find a cool, temperature-controlled, and dry location to store your lithium-ion batteries. Places like refrigerators, garages, basements, and bathrooms are not recommended for battery storage.
Now that you''ve learned all the guidelines and requirements about lithium-ion battery storage, your lithium-ion batteries will be stored safely if you make sure to keep them at the correct temperature, humidity, and in the correct state of charge.

I have a 20ah lithium ion ebike battery that I need to store for three months. Due to inclement weather I will be unable to ride the bike to deplete the battery to 50% or so. The bike is stored inside our air-conditioned condo. I think the current SOC is approximately 80%. What is the risk of leaving it in this state? Would removing the battery from the bike help? Thanks!
According to you, the environment in which the e-bikes are parked is very good. You need to recharge at 1 month intervals to prevent the lithium battery from discharging naturally and going into deep discharge mode (below 20% charge), which will affect the life of your lithium battery. At the right indoor temperature, lithium batteries are safe and will not cause other dangers.
Need to store lithium-ion battery in Reno Nevada for the summer. Temperature get above 100 degrees during that time. Have refrigerator on in house, but have air conditioning set at 90. Where can I store it?
The optimal temperature range for lithium batteries is 10°C to 50°C(122℉) to maintain them in optimal operating conditions and to ensure the performance and lifetime of the energy storage system. Within the temperature range you mentioned, it is not affected, please don’t worry.
So where should you store your lithium batteries if you shouldn’t store them in the basement, garage, or bathroom…in the bedroom, kitchen or dining room? I am at a loss as to where to store them. I certainly don’t feel comfortable storing them in the house.
I have a riding mower that has lithium ion batteries. They look like suitcases. They are in the mower inside a shed. It can get a bit hot in there. Should I take them out of the mower and put them where it''s cooler? I know in winter to take them out. I also have an e-bike but it''s inside. Should I take the battery off the bike when not in use. Please advise.
