Possible reasons and repair methods for lithium batteries that cannot be charged

There may be many reasons why lithium batteries cannot be charged. Here are some common problems and their corresponding repair methods:< /p>

Battery Aging

If the battery is used for too long, the internal chemicals will react ineffectively, preventing the battery from load. In this case, the best solution is usually to replace the battery. When purchasing a new battery, be sure to choose a model that is compatible with your original device.

Charging interface failure

A charging interface failure or poor contact may prevent current from transmitting normally, making it impossible to charge the battery. You can try using a cotton swab dipped in alcohol to wipe off delicatePlease clean the charging interface to remove dust and oxides to restore a normal connection.

Circuit failure

A circuit failure inside the battery may prevent normal transmission of current. In this case, the battery must be disassembled for inspection and repair. When carrying out circuit inspections, be sure to pay attention to safety to avoid dangerous situations such as short circuits.

Repair method

Fast charging method: Use a high-power charger or a charger in a fast charging station to charge the lithium battery. A quick charge typically only takes two hours. After charging, use a multimeter to check if the voltage increases. If the voltage increases, it means the repair effect is good. At this point you can switch to a charger suitable for the battery and continue charging until it is fully charged.loaded.

Slow charging method: Use a low-power charger to charge the lithium battery. After charging for about two hours, replace it with the original charger to complete the remaining charging process.

Parallel repair method: Find a new battery with the same specifications as the original battery, and use wires to connect the old and new battery in parallel. The old battery will start to discharge. After discharging, check if the voltage increases. If the voltage increases, it means that the old battery has been repaired and can then be charged.

Please note that the above repair methods are suitable for batteries that have not reached the end of their service life. If the battery has been severely aged or damaged, its function may not be restored by simple repair methods. In this case, replace the battery witha new one is a safer and more reliable option. Before performing any form of battery repair, make sure you have the proper knowledge and tools to avoid personal injury or property damage. If you are unsure how to do this, it is recommended to contact a professional repair service provider.

Teach you how to activate the lithium battery if it is exhausted and cannot be recharged

Once the lithium battery is exhausted, it will need to be not charging serious negative impact on the battery will directly shorten the life of the lithium battery.

Nowadays, lithium batteries are commonly used in electronic products. When using lithium batteries, it is best not to deplete the battery before recharging, as this will reduce the battery's chemical activity. Therefore, when using dailyelectronic products, you should generally charge them when they still have more than 30% charge. This is a more efficient method to extend the battery life cycle.

Second, because lithium batteries are chemical batteries, after manyAfter the first use, a chemical reaction will occur between the battery electrolyte and the metal plate. A passivation layer will appear on the surface of the metal plate. The passivation layer will prevent current generation and flow, thereby increasing internal resistance. drums. The power that can be supplied will also decrease, causing the battery's capacity to slowly decrease, making it less and less durable.

Detailed information

Lithium battery maintenance precautions:

1. Charge correctly. The number of charges is closely related to battery life. You can use thissome auxiliary software to manage battery or extend battery life with multiple micro-charges.

2. Try to use the original charger and data cable, or use charging equipment matching the output power of the original charger and data cable.

3. Avoid excessive battery temperature. For example, when the body of electronic products such as mobile phones and tablets overheats, the batteries of electronic products will be quickly consumed regardless of whether they are used or not.

People's Daily Online - Are electronic product batteries becoming less durable? When the battery reaches 30%, you need to continue your life

1 Use the charger on a fast charging station to charge: Lithium batteries tend to lose power if they are left in place. a long time. If you want to activate themer, you can directly push the electric car to a fast charging station on the street and find such a charger to charge it. The current in such places is usually relatively large, and the battery can be activated quickly, then it can be replaced with a corresponding charger and continue to be fully charged.

2. Use a high voltage charger to charge: Find a high voltage charger to charge the low voltage lithium battery. Normally, it is better to use a charger suitable for the battery, which is better for the battery. However, if the lithium battery cannot be charged due to power loss, you can use a high voltage charger to charge it to activate the battery.

3. Turn on the headlights when charging, then recharge: If the scooter remains without charge for a long time and the lithium battery "starves", youcan turn on the headlights while charging and then recharge. Connect the charger and see if the charging light on the charger changes. If so, it can charge normally.
