We are all familiar with the comparison of lithium-ion and lead-acid battery maintenance and are aware that lithium-ion batteries require little to no maintenance. However, there has been no clear guidance about lithium batteries use strategies Some believe that the new battery must be fully charged for 12 hours before being emptied and that the maximum capacity can only be activated three times in a row. Others argue that in order to facilitate maintenance, a full charge and discharge process should be performed once a month.battery-storage-clean-energy-electric-industry

Lithium Batteries Use Strategies About Charging Method

“The ideal battery life is to charge it to 80 percent, then disconnect it, let it drop to 40 percent, and then resume charging,” said Isidor Buchmann, CEO of Cadex Electronics, in a recent article. This statement’s theoretical basis is related to the working characteristics of lithium batteries. Correctly charged Lithium Batteries Use Strategies can effectively extend battery life.  The lithium ions that feed the voltage into this battery are critical to its ability to store electricity. The more electricity charged, the higher the voltage intensity and pressure that a single lithium ion must carry. Excessive load over time can significantly reduce the battery life cycle. According to statistics, the same type of battery can only maintain 1500-2000 healthy cycles when fully charged and discharged (100 percent). If the discharge begins at 70%, the number of healthy cycles increases to 2200-3000.

Your battery self-discharge to deplete by 5% every month. While it is generally best to avoid draining a lithium battery, draining it almost once a month may help extend its lifespan. This contributes to the battery’s life cycle time. Keep an eye on your battery to ensure it does not drop below about 5%. Connect it to the charger once you’ve reached this point. Allowing the battery to completely discharge may cause permanent damage and instability. The battery management system(BMS) that monitors battery status can significantly improve lithium battery storage time.

Shallow discharge and shallow charge are better for lithium batteries. Deep discharge and deep charge are required as long as the product’s power module is calibrated for lithium batteries. As a result, products powered by lithium batteries, do not pay attention to the depth of each charging cycle. Use Lithium Battery product should be convenient first and charge at any time, which is more conducive to prolonging the life of lithium batteries.


Lithium Batteries Use Strategies About Charger

Please use a charger designed specifically for Li-ion batteries. A component in lithium battery chargers allows them to adjust charging based on how well the battery is charged. Using an appropriate charger reduces the risk of battery damage. Use the battery charger that came with the battery whenever possible. If you’ve misplaced your charger or need to borrow one, make sure it’s designed for lithium batteries.

When the lithium battery has been fully charged, the charger reduces the current. In addition, the charger may turn on the battery to discharge some power, preventing the battery from overcharging. Although there is a battery management system(BMS) to prevent accidents, it is best not to overcharge the battery for an extended period of time. Batteries age naturally, and high temperatures accelerate this process. The high temperature caused by intermittent charging will create air bubbles in the battery, which will be fatal to the battery’s health. Therefore, not only should pay attention to timely charging and discharging, but also pay attention to the working environment of the product and get timely heat dissipation.

Lithium Batteries Use Strategies About stored

Please keep the following in mind if you want the battery to be temporarily stored independently:

1. Lithium batteries should be stored in a cool, dry and safe environment with a temperature of -5 to 35 °C (95 °F) and relative humidity of not more than 75%. Note that storing the battery in a hot environment will inevitably cause corresponding damage to the lifetime of the battery.


2. Avoid placing lithium batteries near heat sources, open flames, flammable and explosive gases, and liquids, which may cause battery leakage, heat generation, smoke, fire and explosion.


3. If the lithium battery needs to be stored for a long time (more than one month), the battery power should be kept at 30% to 50% of the nominal capacity, and the battery needs to be replenished for 1-2 hours per month during storage.


4. Batteries should be packaged in boxes for transportation. During transportation, violent vibration, impact, or kneading should be avoided, and sun and rain should be avoided. Vehicles such as cars, trains, ships, and planes can be used for transportation.


5. During the storage process of lithium batteries, metal objects should be avoided from entering the battery box, which may cause leakage, heat, smoke, fire and explosion of the battery.


6. If the lithium battery is used in an environment higher than the specified operating temperature, that is, above 35°C, the power of the battery will continue to decrease. If the lithium battery is charged at such a temperature, the damage to the battery will be even greater. Therefore, trying to maintain a suitable operating temperature is a good way to extend the life of lithium batteries.
