Reactivating the battery requires a higher voltage and instant charging with large current (note the "instant", just touch it a little). If you do not have such equipment yourself, you can take it to a cell phone repair shop and ask them to do it for you. If the lithium battery is not used for a long time, it should be charged (about 70% charged) and stored separately, and recharged every 5 or 6 months. Otherwise, the battery will fail easily.
Does the battery of the Canon digital camera I just purchased need to be activated?
For nickel metal hydride batteries, it takes more than three charges and complete discharges before they can be used. fully activated. This approach does not apply to lithium batteries. Lithium batteries are fully activated when they leave the factory and you do not need totake care to carry out activation work.
Lithium batteries should not be deeply charged or discharged. Therefore, when using lithium batteries, avoid overcharging them and never charge the battery until the camera turns off automatically. Instead, charge it when the camera asks you to replace the battery.
How to activate the lithium battery when it cannot be charged
The camera battery has been fully activated before leaving the factory and you do not have no need to activate it again. The claim that it took more than 10 hours to charge the first few times is for nickel-cadmium batteries which have a strong memory effect. It makes no sense for lithium batteries which do not have a memory effect. Three charges, three discharges, full charge, discharge, etc. are all obsolete!
Today's lithium batteries mustonly be fully charged (the charger light turns green). It can be recharged at any time.
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. Replace with a new device 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 mOh, and the nickel-hydrogen battery is only 800-900 mAh; and the capacity of lithium-ion mobile phone batteries is generally between 1300-1400 mAh, so 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 consist of 5 cells.the individual ones. The charging voltage of a single battery generally does not exceed 1.55V and total. The battery pack voltage does not exceed 7.75 V. When the battery pack is when the total charge voltage is less than 8.0 V, it may be a nickel-cadmium or nickel-hydrogen battery .
4. For the original battery, its surface color and glossy texture should be clear, uniform, clean, without obvious scratches or damage; the battery brand should be printed with the battery model, type, rated capacity, standard voltage, positive and negative electrode marks and 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 mobile phone we purchase does not conform to the above phenomenon, we canWe first conclude that it is a fake.
5. From their own perspective, many mobile phone manufacturers have made efforts to improve their know-how to make mobile phones and accessories more difficult to counterfeit, thereby further curbing the proliferation of counterfeiting 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, whenIf the supply current is too large, the power supply will be automatically cut off, resulting in charging failure under normal conditions of the battery, 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.
