PSP1006 cannot be turned on. You can enter the debugging mode. The green light will go out after 5-6 seconds. The same thing will happen if you take out the battery and plug it in. Please ask an expert for guidance on repair.

Myth 1: After buying a PSP, you need to charge and discharge it three times to activate the battery.

Unless the PSP you buy is a product that has been in stock for more than one year, there is no need to do this, because the current battery cells have been activated when leaving the factory, and the cells are packaged into PSP batteries. It has also undergone an activation test, so the battery you get has already been activated. Three more charging and discharging processes will only increase the loss of the battery unnecessarily.

Myth 2: The first charge must last for 12 hours

This is applicable to those early nickel-metal hydride battery devices without battery control circuits, but for today’s smart charging and discharging devices The PSP control module is a joke. When the PSP battery is full, the charging current will be automatically cut off and the system will display it as "external power supply". Even if you continue to charge for 120 hours, the status will not change. Generally speaking, it is fully charged in 3 hours, and the remaining "charging" is just a waste of your time. Instead, when you get a new machine, you should discharge the battery first and then charge it.

Myth 3: The battery needs to be fully charged and discharged once a month.

For nickel-metal hydride batteries with strong memory effect, this is necessary work, but for lithium batteries, this cycle is too frequent. Lithium batteries theoretically eliminate the memory effect. Even if there is, it will It has been greatly weakened to a negligible level. If you use the battery frequently, then you should discharge the battery to a relatively low level (about 10~15) before charging, but if it is discharged to the point where the machine cannot even be turned on (0~1), It is a deep discharge that causes great damage to lithium batteries. Generally speaking, this operation can be done once every 2 months. If you rarely use the battery, then just do this once every 3 months.

Myth 4: Working while charging, or continuing to use an external power supply after charging is completed will damage the host and battery

This is the most ridiculous argument. How many reactions can we get from the theoretical arguments on the so-called hole electron, secondary charging and other mechanism levels in practice? First of all, the views of the battery industry academic community on this are not unified. There are still differences in theory. How can it be used to guide consumers in practical use?

Battery loss is divided into normal loss and harmful loss. The degree of loss caused by the use of external power supply and use while charging is completely within the normal loss range of the battery. In other words, no matter how systematic the battery is, According to theoretical maintenance measures, batteries will age. This is just like how magical cosmetics and maintenance can't prevent a beautiful woman from turning into an old woman. At most, it can only delay it. But how much real effect can the superficial whitewash have? It cannot be explained by theory - respecting actual experience is the correct and scientific view of understanding.

Some people may say that the only way to avoid battery aging is not to use it (so many people will choose to remove the battery), but this makes the PSP portability meaningless, and secondly, even if the battery is in a sealed state It also ages naturally over time. Batteries are actually semi-consumables. As long as batteries bring you enough convenience and happiness, I think their sacrifice is valuable.

Therefore, the generally accepted opinions on battery maintenance and usage are as follows:

1. Complete discharge (use until black screen and power off) should be avoided

2. Frequently charging and discharging the lithium battery, charging it when it is not fully discharged, or using an external power supply, using it while charging, or continuing to use an external device after charging is completed will not cause additional losses to the battery.

2. When not in use for a long time, the lithium battery should be taken out and placed in a cool and dry place. Never freeze to avoid water vapor erosion. Avoid using it in a hot car. If stored for a long time, charge the battery to 40% and then place it.

3. As a notebook user, if you use a fixed power supply most of the time, you can remove the battery and place it in a cool place, but this is only for the sake of battery safety. Improvement of environmental factors such as temperature and humidity.

As for the PSP, using an external power supply with the battery installed will not cause additional damage to the battery. And out of the concept of portability and protection of the battery cover and metal contacts, it is recommended not to frequently disassemble the battery due to the use of external power supply.

4. Avoid purchasing spare lithium batteries for storage, because even if the battery is not used, its service life is naturally reduced. Therefore, within the limited survival time of the battery, maximum use is the best way to reflect it. The value of the battery is not a PSP to torture yourself with all kinds of unrealistic theories and for entertainment.
