This is because the battery protection circuit is locked at this time, even if you continue charging, it may not be able to activate.
If you use it frequently, the battery life will soon be reached and damaged.
If you notice this and charge it regularly at regular intervals to prevent the battery from getting stuck, then even if the lithium battery is not used and well maintained, it will still age, and this aging period will almost end in two years.
So try to buy models with replaceable batteries.
Battery refers to a cup, tank or other container or part of a composite container containing an electrolyte solution and metal electrodes to generate electric current. It is a device capable of converting chemical energy into electrical energy. It has pos polesitive and negative.
With the advancement of technology, batteries generally refer to small devices that can produce electricity. Like solar cells. Battery performance parameters mainly include electromotive force, capacity, specific energy and resistance.
Using the battery as a power source can achieve stable voltage, stable current, stable power supply for a long time and little influence from the outside world. In addition, the battery structure is simple, easy to carry. and charging and discharging operations are simple and easy. It is not affected by external climate and temperature, has stable and reliable performance, and plays a great role in all aspects of modern social life.
Lithium batteries have always had self-discharge characteristics. If they are not used for a long time andare not charged in the middle of the period, self-discharge will cause battery exhaustion. power, causing the battery voltage to be too low. No power is coming.
1. Low voltage charging, use a charger with lower voltage than original. When the battery is charged to 20%, the voltage will return to the value, then replace it with the original charger. .
2. Single battery charging, charge each battery individually in the battery pack, but pay attention that the voltage of the charger is consistent with that of the single battery. This method takes a long time to restore the battery. recharge for a long time.
3. Special charging method, use special charger with repair function. Regardless of the voltage drop due to self-discharge, this charger can charge the lithium battery after the lithium battery is fully charged. , all aspectsBattery performance has also been restored.

Lithium batteries for mobile phones are mainly composed of upper and lower plastic shells, lithium batteries, protective printed circuit boards (PCBs) and resettable fuses (polyswitch). Some manufacturers also configure components such as NTCs, ID resistors, vibrating motors or charging circuits. Lithium batteries are durable goods, so they are not delicate. You can treat them with peace of mind and there is no need to equip them with expensive original chargers. Generally, an ordinary branded base charger is enough, and the price is 15-20 yuan, which eliminates the restriction of relying on mobile phones for direct charging.
