Lithium battery is a common rechargeable battery, which has the advantages of high energy density, low self-discharge and no memory effect. However, lithium batteries also have some shortcomings, such as easy to overcharge and overdischarge, affected by temperature, aging and so on.

So, if you encounter a 12v lithium battery can not be charged how to repair? Here are some common lithium battery repair methods.

First, 12v lithium batteries do not charge into the cause

1. Charger failure: charger failure is one of the common causes of 12v lithium battery charging. Usually, the charger will not be able to charge properly because of the internal electronic components are damaged or poor contact.

2. Battery failure: battery failure is also one of the common causes of 12v lithium batteries do not charge. Battery failure is usually manifested in the battery internal short circuit, plate corrosion or battery expansion and other problems, these failures will lead to the battery can not be normal charging or charging effect is poor.

3. Charging environment is not suitable: the charging environment is not suitable may also lead to 12v lithium batteries can not be charged. For example, charging in too high or too low temperature environment, or charging in a humid environment may cause damage to the battery, resulting in failure to charge properly.

4. Incorrect charging method: If you use an incorrect charging method, it may also lead to 12v lithium batteries can not be charged. For example, the use of too low charging current or too high charging voltage, may cause damage to the battery, resulting in failure to charge properly.

Second, 12v lithium battery charging repair method

1. Replace the charger: If the charger failure leads to 12v lithium batteries can not be charged, the simplest way to repair is to replace a new charger. When buying a new charger, you need to pay attention to choose the charger model and specifications to match the battery.

2. Repair the battery: If the battery failure leads to 12v lithium batteries can not be charged, you can repair the battery failure according to the specific reasons. For example, if the battery internal short-circuit caused by the inability to charge properly, you can try to repair the short-circuit parts; if the battery pole plate corrosion caused by the inability to charge properly, you can try to use a special repair agent to repair; if the battery expansion caused by the inability to charge properly, it is recommended to replace the battery.

3. Improve the charging environment: If the charging environment is not suitable to cause 12v lithium battery can not be charged, you can try to improve the charging environment. For example, when charging at too high or too low a temperature, you can take some measures to reduce the temperature or increase the temperature; when charging in a humid environment, you can take some measures to reduce the humidity or increase the humidity.

4. Use the correct charging method: If you use the incorrect charging method to cause the 12v lithium battery can not be charged, you can take the correct charging method to repair. For example, when using a charger for charging, you need to pay attention to selecting the correct charging current and voltage; when using mobile power for charging, you need to pay attention to selecting the correct output current and voltage.

In short, for the 12v lithium battery charging problem, we can take a variety of repair methods to solve. When using these repair methods, you need to pay attention to safety issues and use the appropriate tools for operation. If the above methods are unable to solve the problem, it is recommended to contact professional maintenance personnel for inspection and repair.
