How Long Do Lithium Batteries Last in Storage?

2024-07-04

Lithium batteries have emerged as a promising option for all those wanting to set up a power generation system, whether at a smaller or larger scale. 


Before making a choice, it is imperative to investigate a few essentials such as battery storage life span etc. 


So, how long do lithium batteries last in storage? Let's dig deep into all the essential points and aspects to find an accurate answer. 


How long do lithium batteries last in storage?


Finding out the exact period for the longevity of the batteries is a very complex task. It has an extensive range of factors involved, which can deteriorate or enhance the overall lifespan of the battery in storage. The same is why it becomes nearly impossible to tell an exact number. 


However, on average, a lithium battery can last from 2 years to 10 years in storage, depending upon the conditions they have kept in. In addition, the quality of the purchased battery plays an equally significant role. 


Factors that affect the lithium battery in storage - best practices to increase the lifespan


The storage capacity of lithium batteries can be affected by an extensive range of factors, some of which are mentioned as follows. In addition, find out about all the best practices you can consider for enhancing the lifespan. 


1. Charging cycles


The charging cycle refers to the total time you charge a battery to its 100% capacity. For instance, if you have charged the battery eight times to 100% and two times 50% each, its lifespan would count to 9  charging cycles. 


As time passes, the lifespan of the charging cycles starts to shrink, causing the storage system to lose charging frequently. 


If you consider chagrin the battery once it's fully used and does not unplug the socket until it's fully charged, the storage capacity remains stronger. However, if you frequently charge your battery without draining it to the fullest, the storage capacity of the lithium battery may deteriorate. Thus increasing the number of charging cycles. 


2. The impact of discharging


Discharging is another crucial factor in the lifespan of batteries kept in storage. It symbolises the total percentage of the battery that has been used so far. 


What only a few people realise is that each time you discharge your battery, it has a significant impact on the overall battery life- especially if it's kept in storage without usage. 


3. State of SoC


Storing lithium batteries at SoC for 40 to 50 percent is ideal to ensure a durable life span in storage. If you keep the state of charge between 40 to 60 percent during the usage, you are actually minimising the stress on the chemical structure. 


The lithium batteries have a lower degree of recharge in comparison to other options available in the market. It will be at most 2 to 3 percent generally. 


4. Temperature


Temperature is another element that can affect the lifespan of your lithium battery in long-term storage. It is imperative to keep an eye on the temperature, which must not exceed 20 degrees Celsius. 


If the temperature exceeds this range, the chemical reactions of the battery can get imbalanced, causing significant losses to the health as well as to the environment. 


Not only high but too much low temperatures can also result in the loss of battery health during storage. 


5.  The degree of physical protection


Storing lithium batteries accurately is another factor to consider for enhancing their lifespan. It is best to store the batteries in their original packaging because these are specifically designed to protect the batteries from outside pollutants. 


If you have lost it, consider storing the battery in shields which don't get affected by the vibrations and other mechanisms. Do not use glass elements as these can crack or cause leakage, which you don't want. 


6. Battery formulation


Different lithium batteries have distinguished battery formulations. Lithium-ion and lithium polymer are two significant types of it. 


The period of the batteries in storage also differs from type to type. If you own a lithium polymer battery, you can expect a shorter storage lifespan such as between 1 to 3 years. 


The reason is that these batteries are extremely sensitive to temperature and stress and can get drained easily if not used for a long time. 


On the other hand, lithium-ion batteries are more durable and can withstand higher and extremely lower temperatures for years. 


7. Charging voltage


If you want to increase the lifespan of your lithium battery in storage, it is optimum to use the paramount charging voltage while it is in use. Remember, charging above or below the recommended limit can tempt the battery. 


Initially, you might like enjoying the fast charging or an instant power supply, but in the long run, it will decrease the battery health. Thus, ensure to keep the charging voltage between the range of 3.6 to 3.7 volts.


8. Storage conditions


The conditions under which you are storing your battery is another big player in increasing or decreasing its life span.  In the first place, store it under the charge state as recommended by the manufacturer which is usually 50% of the total capacity. 


In addition, ensure that the place has a cool and dry atmosphere and is never exposed to direct sunlight. 


However, the quality of the battery also contributed a lot to the overall lifespan. 


Best Practices for Storing Lithium Batteries


To maximize the lifespan of your lithium batteries, follow these best practices when storing them:


Keep Batteries Cool: Store your lithium batteries in a cool, dry place. A temperature range of 15°C to 20°C (59°F to 68°F) is ideal. Avoid areas that are subject to extreme heat or cold, such as attics, garages, or basements.


Maintain 40-60% Charge: Store your lithium battery with around 40% to 60% charge. This is the optimal charge level to reduce degradation and prevent damage.


Use Original Packaging: If possible, store your batteries in their original packaging. The packaging is designed to keep the battery safe from short-circuiting and physical damage.


Avoid Storing in High Humidity: Humidity can cause corrosion on the battery terminals, which can lead to malfunctions. Always store batteries in a dry environment.


Recheck and Recharge: If you store your batteries for long periods (e.g., several months or more), check their charge periodically. Recharge them to the 40% to 60% level every 6 months or so to prevent deep discharge.


Keep Away from Flammable Materials: Lithium batteries can be volatile, so it’s important to store them in a safe location, away from flammable materials or extreme conditions.
