1. The charger interface is old or the charger itself is damaged. Replace it with a new charger to test it.
2. The metal of the charging hole is oxidized and causes poor contact. This is a hardware failure. You should contact after-sales service for detailed inspection and repair.
3. There is a problem with the quality of the charging cable. Replace it with a new one.
4. The battery itself is exhausted or damaged. Just replace it.
5. Remove the battery after it is completely exhausted and treat it with temperature. If the battery temperature is unstable, the use time will be greatly shortened because the battery has no energy and a considerable part of the battery. The lithium ions are already charged. If you have memory electricity, you can use this method to release some of the memory electricity. WhenWhen winter comes, put it outside for a while, then bring it inside.
6. There is another way to remove the battery and leave it for about a week to slowly consume the power. You must first use a machine to completely consume the energy. Then rinse again. Once it is full, disconnect and rinse again several times.

18650 lithium battery repair principle:
Principle 1: The metal surface of the lithium battery used for a long time will be oxidized to a certain extent If the battery is not in good contact with the mobile phone, the life of the lithium battery will be shortened. Use an eraser or other cleaning tools to remove rusty material on the surface and improve contact. between the battery andmobile phone.
Repair Principle 2: Low temperature can change the electrolyte inside the lithium battery and promote chemical reactions in the newly frozen battery. The process of using a lithium battery is actually a process of charging and discharging.
During this period, the negative and positive charges of the battery collide. The reason why batteries become less and less durable is that at normal room temperature, the internal kinetic energy of electrons is relatively large, so the battery is in an active state and leakage is relatively frequent.
When lithium batteries are placed in a low temperature environment, the microstructure of the lithium film on the surface of the lithium battery and the electrolyte, as well as their interface, will undergo significant changes , causing temporary problems. inactivelife inside the battery and reduction of leakage current. Therefore, after recharging, the battery life of the mobile phone will increase.
Third principle of repair: Deep discharge of the mobile phone involves obtaining a deeper recharge by depleting the internal power, which requires unconventional methods.
Find a way to connect the cell phone to a small 1.5V light bulb. The energy in the lithium battery will be transferred to the small bulb until all the light is emitted . "Cell phones must slowly drain due to lower voltages. Under normal circumstances, if the cell phone is connected and is lower than the rated voltage of 3.6 volts, it will automatically turn off after discharge, the battery of the mobile phone recharged." can be used longer.
How to quickly judge whether a battery ist durable or not
How to tell if a Chaowei battery is old or new:
First of all, when consumers buy batteries, they are the first to see if the Outer packaging of the electric vehicle battery is damaged or broken. Then they open the package to see what the battery looks like and pay. Be careful to check whether there are scratches or scratches on the surface. Check the front and negative metal terminals of the battery for scratches and rust.
In addition, many brands of factory electric vehicle batteries will have a safety label affixed to the battery case. Pay attention to whether the safety label is normal. If necessary, you can scrape off the password coating. on the security label to verify authenticity. Finally, look at the production date on the battery.
At the same time, consumers must remember thatOld and new batteries cannot be connected together. New original batteries are packaged and assembled before leaving the factory. If mixed with old batteries, it will affect the performance of new batteries and cause premature aging of new batteries.

Notes:
p>Lithium batteries
Traditional lead-acid batteries, nickel-cadmium batteries and nickel-metal hydride batteries are technically mature, but their use as power batteries in cars is problematic. Currently, more and more automobile manufacturers choose lithium batteries as the power batteries for new energy vehicles. Because lithium-ion batteries have the following advantages:
High operating voltage (three timess that of nickel-cadmium batteries and hydrogen-nickel batteries) higher energy (up to 165WH/kg, three times that of nickel -metal hydride batteries) volume Small; light quality; long life expectancy ; low self-discharge rate; no memory effect;
Lithium iron phosphate battery
Lithium iron phosphate battery is also a type of lithium battery. Its energy is less than half of that of lithium cobalt oxide battery, but it has high safety and. long cycle times. Up to 2000 times, stable discharge, low price, becoming a new choice for automobile power supply. The industry considers the "iron battery" offered by BYD to be a lithium iron phosphate battery.
Fuel cell
In simple terms, a fuel cell is an electricity generating device that directly converts the chemical energy contained in fuel and oxidizer into energy.electrical engineering. Fuel and air are fed into the fuel cell and electricity is magically produced.
It has positive and negative electrodes and electrolytes and looks like a battery, but basically it cannot store electricity, but it is a power plant. The proton exchange membrane fuel cell is the most promising solution for automobiles.
01
Look at the appearance of the battery for cracks, rust, deformation, etc. If these conditions appear, it means the battery has been refurbished and has a short lifespan. A new battery should be spotless, the writing on the battery should be clear, and the battery should look new.
02
Batteries for electric vehicles generally include lead-acid and lithium batteries. Relatively speaking, lithium batteries have a longer lifespanlonger than lead acid batteries. Battery usage period is about two years, and the life of lithium batteries is 4-5 years. If you want an electric car with longer battery life, choose lithium batteries.
03
Electric vehicles have special batteries When purchasing an electric vehicle, it is best to ask the retailer for the brand of the battery. Battery life. The special battery for electric vehicles lasts longer than ordinary batteries.
04
The battery capacity will be indicated on the surface of the battery. Choose a large capacity battery. If the battery capacity is small, it will need it. Batteries need to be charged frequently, and frequent charging will be easily damaged, affecting their service life.
