Analysis and repair of the reasons why 18650 lithium batteries cannot be charged.
18650 lithium battery manufacturers have a wide range of application fields. However, in daily use, the problem of not being able to charge is a common issue and a headache that often troubles users. So how can 18650 lithium battery manufacturers solve the problem of not being able to charge, and what are the reasons for the inability of 18650 lithium battery manufacturers to charge? Let's explore together the reasons and methods behind it.
1、 There are several reasons why 18650 lithium battery manufacturers cannot charge:
1. Internal charging circuit malfunction, unable to charge normally.
2. There is an internal malfunction in the 18650 lithium battery manufacturer.
3. The battery electrode contact is dirty and the contact resistance is too high, causing a large voltage drop. When charging, it is considered that the host is full and the charging is stopped;
2、 Solution for 18650 battery not charging:
1. The charger interface is aging or the charger itself is damaged. Replace the charger with a new one for testing.
2. The quality of the charging circuit is problematic. Replace the pipeline with a new one.
3. The metal in the charging hole was oxidized, resulting in poor contact, which is a hardware failure and requires detailed maintenance after sales. The battery itself has been depleted or damaged, please replace it directly.
3、 18650 lithium battery manufacturer repair principle:
Repair principle 1: Long term use of lithium battery manufacturers may result in a certain degree of oxidation on the metal surface, leading to poor contact between mobile phone batteries and phones. Lithium battery manufacturers use rubber camphor or other cleaning tools to remove surface rust and allow the battery to continue to come into contact with the phone. Act better.
Repair principle 2: Deep discharge of mobile phones is achieved by depleting internal electrical energy to achieve deeper recharging, which requires some non-traditional methods. Find a way to connect your phone to a 1.5-volt light bulb. The electricity inside the lithium battery manufacturer will be transmitted to the small light bulb until all the lights are on. Mobile phones need to slowly drain their power supply through a lower voltage. Normally, if the connection voltage of the phone is below 3.6 volts, the phone will automatically shut down. Charging allows the battery to last longer.
Repair principle 3: Low temperature can change the electrolyte of lithium battery manufacturers and promote the chemical reaction of newly frozen batteries. The use of lithium battery manufacturers is actually a charging and discharging process. During this period, negative and positive charges in the battery collide with each other. The reason why batteries are becoming increasingly impractical is that at normal room temperature, the internal energy of electrons is relatively high, so batteries are in an active state and leakage is relatively frequent. When lithium battery manufacturers are placed in a low-temperature environment, the microstructure of the lithium film and electrolyte on the surface of the lithium battery manufacturer, as well as the interface between lithium battery manufacturers, undergo significant changes, resulting in inactivity inside the battery and reducing leakage current. So after charging, the standby time of the phone will increase.
The cycle life of lithium battery manufacturers is about 600 times. If charged multiple times, the thermal motion of molecules will gradually disrupt the internal arrangement and structure of the molecules, and the efficiency of storing charges will gradually decrease. The process of "freezing" can easily damage the original internal structure of the battery, and the charging capacity may increase in a short period of time, but long-term use may not be effective. Once the microstructure of lithium battery manufacturers is damaged, it is impossible to fully restore it. Long term use of this method will accelerate the wear and tear of mobile phone batteries.
4、 Repair methods for 18650 lithium battery manufacturers:
1. After the battery is fully used, remove it and use the temperature for processing. When the temperature is unstable, the battery can greatly shorten its usage time because it has no electricity. A large part of the lithium ions have memory, so in winter, some of the memory can be discharged outside for a period of time and then returned to the house.
2. Another method is to remove the battery and leave it aside for about a week, which will slow down the power consumption. It needs to be completely consumed by the machine first. Then make full use of it. It is estimated that your current charging time must be very short. When it is full, it will be cut off and repeated several times, which will definitely be effective.
