Is there a safety hazard when the mobile phone battery is put on for a long time?

1. Is there a shelf life of the lithium-ion battery? Should it be destroyed by the shelf life? The shelf life of lithium battery is actually the battery life, it can be charged and discharged more than 500 times, and it is 2-3 years according to normal use. But your situation is not used then battery life is almost equal to stagnant state. As long as it is free from moisture, pressure, high temperature and low temperature, this storage period is close to infinity in an ideal environment.

2. If you take it out and recall it occasionally, is charging and charging extremely dangerous? Not only is it not a dangerous act, but it is a very correct approach. The battery will not self-discharge for a long time. When the placement point is too low than the battery charging threshold (usually about 3.3V), the protection circuit will start. You can always charge the battery in the normal way, which is equivalent to the battery dead. Therefore, taking 3 months to do a full charge and discharge is beneficial to battery storage, and lithium ions need to be exercised.

3, even if there is no fire explosion (or the probability is small can be ignored), then there is no battery leakage corrosion components (after all, I still want to keep a commemoration, do not want to be eroded) normal environment storage fire explosion probability is close infinitely small, can be ignored. However, leakage is very common, and the environment may be wet. Soaking water may cause it. So check the battery package for any leaks before use.

4. What do I need to do to save these phones, and I can basically guarantee that they will not happen (that I don't want to see)? Remove the battery and save it separately. It is recommended to use a plastic bag to squeeze out the air and approach the vacuum. It can avoid water ingress and avoid moisture in the air. Regularly power-on to avoid the tide of the internal lines of the mobile phone, basically it can be stored for 20 or 30 years.
