What Should I Pay Attention To When Using Lithium Batteries?

Since the advent of lithium batteries, they have developed rapidly due to their excellent performance and incomparable advantages, and have been widely used in various scenarios, quickly occupying many fields. But the way most people use and maintain lithium battery packs is not very clear. In order to use lithium batteries better and more safely, lithium batteries manufacturer will take you to know what to pay attention to daily.

1.Precautions for lithium battery charging

Lithium batteries are strictly prohibited to be charged from the discharge terminal, and must be charged from the charging socket with the matching special charger. When the charging indicator bar on the charger stops scrolling, please remove the charging plug in time to avoid overcharging the battery.

2.Notes on discharge

The lithium battery pack has an overcurrent protection function. When the use current of the electrical equipment exceeds the maximum output current of the product, the overcurrent protection circuit will act and make the electrical equipment appear to be unable to work normally.

3.The newly purchased lithium batteries

The newly purchased lithium battery has a little power, so users can use it directly when they get the battery, and recharge the remaining power. After 2 to 3 times of normal use, the lithium battery activity can be fully activated. Here is a special reminder: Don’t misbelieve the rumors from the salesperson or the Internet, the new lithium battery needs to be activated for up to 12 hours when it is first used.

4.When charging the lithium battery

Lithium batteries do not have a memory effect and can be charged as they are used, but it should be noted that lithium batteries cannot be over-discharged. Over-discharge will cause irreversible capacity loss. When the machine warns that the battery is low, it will start charging immediately. Don't use it in a hurry after charging. In daily use, put the newly charged lithium battery for half an hour, and use it after the charging performance is stable, otherwise it will affect the battery performance.

5.Lithium battery use environment and maintenance methods

When not in use, such as laptop lithium batteries, be sure to take out the batteries and store them in a dry and cool place. Note that the charging temperature of the lithium battery is 0 ℃ ~ 45 ℃, and the discharge temperature of the lithium battery is -20 ℃ ~ 60 ℃. Avoid frequent overcharging. Overcharging will cause the temperature inside the battery to rise to a high level, which is harmful to the lithium-ion battery and charger. Therefore, a full charge is enough to turn your lithium battery into a small bomb.

Summary: The battery is a consumable product, and its life span is fixed (the number of charging and discharging is usually 300-500 times), so mastering the correct method of use is the secret of battery life extension.

6.Battery maintenance for the correct use of lithium battery packs

Charging: The safe working voltage range of lithium battery is 2.8~4.2V, lower or higher than this voltage range, the lithium ion in the battery becomes very unstable and even causes accidents. To ensure that the battery is in a safe range, a special charger is needed. Lithium batteries need to be charged and discharged every three months to restore their original performance. Before using the lithium battery, check whether it meets the requirements of the load. Using it under conditions that cannot meet the load requirements or high current (over 1C) will damage the battery or shorten its life. Avoid frequent use in high or low temperature environments. It is best to be at room temperature, as temperature has a great influence on the characteristics of lithium batteries.

7.How to store lithium battery without long-term use

Lithium batteries should be charged with 50%~80% of electricity if they are not used for a long time, and they should be taken out of the instrument and stored in a dry and cool environment. The batteries should be recharged every 3 months to avoid excessive storage time. The battery is too low due to self-discharge, causing irreversible capacity loss. The self-discharge of the lithium battery is affected by the ambient temperature and humidity. High temperature and humidity will accelerate the self-discharge of the battery. It is recommended to store the battery in a dry environment between 0 ℃ and 20 ℃.
