With the increasing demand for portable electronic devices, 12V lithium batteries are widely used in various fields as a common power supply device. However, some problems will inevitably occur in the process of use, such as not charging. So, how to fix the problem of 12V lithium batteries not charging? The following is a detailed introduction for you.

First, check the charger

First of all, you need to check whether the charger is working properly. You can try to use other chargers to charge the battery, or connect the charger to other batteries to check. If there is a problem with the charger, you need to replace or repair the charger.

Second, check the charging line

If the charger is normal, then you need to check whether the charging line is well connected. Check whether the connection line between the battery and the charger is firmly connected, if found loose or broken, you need to replace or repair the line.

Third, check the battery

If the charging cable and charger are fine, then you need to check whether the battery itself is faulty. You can try to use a multimeter to measure the voltage and internal resistance of the battery, and if you find any abnormality, you need to replace the battery. In addition, it should be noted that when using lithium batteries, you should follow the correct charging method and use specifications to avoid damage to the battery by overcharging.

Fourth, check the charging environment

In addition to the above factors, you also need to check whether the charging environment meets the requirements. If the charging is carried out in high temperature, high humidity, high magnetic field and other environments, it may cause damage to the battery and affect the charging effect. Therefore, you need to ensure that the charging environment is dry, ventilated, no magnetic interference, etc..

In short, for the problem of 12V lithium battery not charging into the battery, you can check and repair from the charger, charging line, battery itself and charging environment. In the repair process, you need to pay attention to safe operation to avoid damage to the battery overcharging. At the same time, in order to extend the service life of the battery, you should follow the correct use of norms, and pay attention to the care and maintenance.
