Lithium batteries do not need to be activated. Possible reasons and solutions for charging failure are as follows:
1. The charger interface is old or the charger itself is damaged. charger to test.
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.
Detailed information
How to identify real and fake lithium batteries:
1. Compare battery capacity. The general nickel-cadmium battery is 500 mAh or 600 mAh, and the nickel-hydrogen battery is only 800-900 mAh; and the capacity of lithium-ion cell phone batteries is generallyent between 1300-1400 mAh, so that the usage time of the lithium battery after being used. fully charged is about 1.5 times that of nickel-hydrogen battery, or about 3.0 times that of nickel-cadmium batteries.
2. Look at the plastic surface and the plastic material. The original battery has a uniform wear-resistant surface and is made of PC material, which is not fragile. Counterfeit batteries do not have a wear-resistant surface or are too rough and are made from recycled materials that are prone to brittleness.
3. Measure the charging voltage of the battery pack. If a nickel-cadmium or nickel-hydrogen battery pack is used to simulate a lithium-ion cell phone battery pack, it must be made up of 5 individual cells. The charging voltage of a single battery generally does not exceed 1.55V and total. Battery pack voltage ne does not exceed 7.75 V. When the battery pack is when the total charging voltage is less than 8.0 V, it may be a nickel-cadmium or nickel-hydrogen battery.
4. For original batteries, the color and texture of the battery surface should be clear, uniform, clean, without obvious scratches or damage; the battery brand must be printed with the model, type and rated capacity of the battery. , standard voltage and normal voltage. Negative pole mark, manufacturer name.
It must be smooth and unobstructed, have a suitable seal, fit the hand well and have reliable locking; the material must not have obvious scratches or black or green spots. If the battery of the cell phone we buy does not conform to the above phenomenon, we can initially conclude that it is fake.
5. From their own point of view, many phone manufacturersmobile phones have made efforts to improve their know-how to make mobile phones and their accessories more difficult to counterfeit, thereby further curbing the proliferation of counterfeits and parallel imports. Generally, ordinary mobile phone products and their accessories should have a consistent appearance.
6. Observe charging anomalies. Generally, genuine cell phone batteries must have an overcurrent protector inside, which automatically cuts off the circuit when an external short circuit causes excessive current to avoid burning or damaging the phone. Lithium-ion batteries also have an overcurrent protection circuit, which can be; used when non-standard electrical appliances are used, when the power supply current is too large, the power supply will be automatically cut off, resulting in failure ofWhen charging under normal battery conditions, it can automatically return to the conductive state. If during the charging process we find that the battery seriously overheats, smokes or even explodes, it means that the battery must be fake.
