Mobile phone lithium-ion batteries have a limited lifespan, and their performance will significantly decrease if they are not used for extended periods in daily life. So, how should we properly store batteries? Here are some tips for storing mobile phone lithium-ion batteries.
01. Suitable usage and storage environment
Both lithium-ion and nickel-ion batteries have strict requirements for the temperature and humidity of their storage environment. Among all environmental factors, temperature has the greatest impact on battery charging and discharging. The electrochemical reactions inside lithium-ion batteries are related to ambient temperature. If the temperature is too low, the battery will have no voltage output, making it unable to power on. If the temperature is too high, the battery's self-discharge rate will accelerate, which is not conducive to long-term storage.
Tips: The operating temperature range of mobile phone lithium-ion batteries is -20℃ to 60℃. Generally, the maximum temperature limit for mobile phone batteries is 40℃. However, it is still important to note that the charging and discharging temperature should not be below -10℃ or above 45℃, as this will reduce charging efficiency and may lead to dangerous situations such as battery leakage.
Short-term storage: Store the battery in a dry place free from corrosive gases and with a humidity level between -20°C and 35°C. High or low temperatures may cause the battery's metal parts to rust or the battery to leak.
Long-term storage: Long-term storage can cause passivation of battery activity and accelerate self-discharge rate. The ambient temperature is best between 10℃ and 30℃. In addition, a charge-discharge cycle should be performed every 3 months to maintain its activity and restore its performance.
02. Correct usage method
Batteries are consumables with a limited lifespan, typically 300-500 charge-discharge cycles. Therefore, mastering the correct usage methods is the secret to extending battery life.
Lithium-ion batteries typically have comprehensive protection circuits, so charging usually doesn't present significant problems or limitations. However, to prevent safety issues caused by overcharge protection failure, prolonged charging is not recommended. Removing the battery immediately after it's fully charged is the best practice. Furthermore, it's best to use the original charger and charging cable, as this best meets the charging power requirements of your current device and is the safest and most efficient charging method.
