Equipment required to repair lithium batteries includes: battery tester, lithium battery charger, battery protection board, battery disassembly tools and repair tools battery assembly.
1. Battery tester
Battery tester is one of the necessary equipment for repairing lithium batteries. It can detect battery parameters such as voltage, current, temperature, capacity and internal resistance. Through the detection of the tester, the condition and problem of the battery can be quickly determined, so that corresponding measures can be taken for repair.
2. Lithium Battery Charger
Lithium battery charger is another important equipment for repairing lithium batteries. Proper charging current and voltage can be supplied to lithium batteries to ensure that the batterie is fully charged and avoid overcharging. In addition, the lithium battery charger can also detect parameters such as battery charging status and charging time to ensure the safety and stability of the battery.
3. Battery protection board
The battery protection board is an important part of the lithium battery and protects the battery from overcharge, overdischarge, short circuit and overcurrent. When maintaining lithium batteries, you should check the condition and performance of the battery protection board to ensure that it is working properly. If there is a problem with the battery protection board, it should be replaced in time.
4. Battery Disassembly Tool
The battery disassembly tool is a tool used to disassemble lithium batteries, helping users easily disassemble the battery for repair.repair and replacement. When using battery disassembly tools, you should pay attention to safety to avoid damage to the battery and your own safety.
5. Battery assembly tool
The battery assembly tool is a tool used to assemble lithium batteries, helping users to assemble batteries together and ensure good and stable connections between them. batteries. When using battery assembly tools, you must pay attention to details to avoid damaging the battery and affecting its performance.
Where to repair a broken lithium battery
There are generally three methods to repair a lithium battery that cannot be charged, namely namely fast charging method, slow charging method and parallel repair method.
It should be noted that if the lifespan of the lithium battery is reached (theThe lifespan of a lithium battery is generally around four years), it cannot be repaired. These three methods are. Applicable only to lithium batteries.
Fast charging method: Use a high-power charger or go to a fast charging station to charge the lithium battery. The quick charge time is checked at around two hours. Once the time is up, use a multimeter. to measure the voltage of the lithium battery. If the voltage is higher than before charging, this proves that recovery is successful. At this time, use the original charger to fully charge the lithium battery.
Slow charging method: The principle is almost the same as the fast charging method. Use a charger with lower power than the original charger to charge the lithium battery. If the original charger is 60V, use a 48V charger. Charge the battery in bedhium for half an hour before using the original charger. There is some probability that the battery can be repaired.
Parallel repair method: Find a new battery with the same specifications as the lithium battery, use wires to connect the old lithium battery and the new lithium battery in parallel. At this time, the new lithium battery will discharge the old lithium battery after a certain discharge time. use a multimeter to check the old lithium battery. The battery voltage is measured and an increase in voltage indicates that the old battery has been successfully repaired.
Precautions for charging lithium batteries
Avoid charging at too low temperatures. If you use lithium batteries in a low temperature environment, i.e. below 4°C, you will also find that the battery lifee the battery is reduced. The original lithium batteries of some mobile phones cannot even be charged in low temperature environments. But don't worry too much, this is only a temporary situation. Unlike use in high temperature environments, once the temperature rises and the lithium-ion battery molecules are heated, they immediately return to their previous power.
Used often. Life is movement. If you want to maximize the performance of a lithium-ion battery, you need to use it frequently to keep the electrons in the lithium-ion battery flowing. If you do not use the lithium battery frequently, remember to cycle the lithium battery charge every month and perform power calibration, that is, deep discharge and a deep load.
Repair locationstion of broken lithium batteries: manufacturers' after-sales service centers, third-party repair shops and electronic product repair centers.
1. Manufacturer's after-sales service center
If the lithium battery is still within the warranty period, you can contact the lithium battery manufacturer's after-sales service center for repair or replacement according to the situation.
2. Third-party repair shop
You can try to go to a professional third-party repair shop for repairs, but you should choose a repair shop with a good reputation and guaranteed service quality to avoid improper repairs . Or the case of replacing inferior batteries.
3. Electronic product repair points
In some large shopping centers or electronic product sales points, there will also be repair pointsrepair of specialized electronic products. You can consult them to see if they can repair lithium. batteries.
Precautions for using lithium batteries
1 Read the battery instructions carefully, use the recommended batteries, and operate according to the operating procedures .
2. Check whether the contacts of electrical devices and batteries are clean. If necessary, wipe them with a damp cloth, install them in the correct polarity direction.
3. Do not let children change batteries without adult supervision. Small batteries such as AAA should be kept out of reach of children.
4. Do not mix new and old batteries or batteries of different types, especially dry batteries and rechargeable batteries.
5. Do not attempt to regenerate the main battery by heating, charging, or other methods to avoid damage.iterate any danger.
6. Do not short-circuit the rechargeable battery, otherwise it will damage the battery and cause it to heat and burn.
