Common misunderstandings of mobile phone rechargeable batteries

Common mistakes and safety solutions for mobile phone rechargeable batteries are the first language for a long time, and news of mobile phone explosions keeps coming. There is a lot of discussion about charging mobile phones, and some charging errors are often confusing. So, how can we charge correctly, not only ensure safety, but also extend the life of the battery? Common misunderstandings 1. How many times does the new battery need to be charged before it can be activated? Different battery products require different charging methods, which must be used according to the product. . Early nickel-cadmium batteries and nickel-metal hydride batteries should be similarly activated. These batteries have a recall effect. They are charged without being fully discharged, which can lead to overcharging and make users feel that the battery is quickly used up. Truth: Most of the batteries used in mobile phones and laptops are lithium batteries. Its initialization process is completed at the time of manufacture, so do not activate it at startup. 2. Can reducing the number of recharges extend the battery life? The life of a typical lithium battery can reach hundreds of charge and discharge cycles. The cycle here refers to the process of letting the battery dry and recharging, rather than plugging the charger in and unplugging it again. Lithium batteries have no recall effect and can be charged at any time. In order to reduce the number of recharges, deliberately recharging the battery after it is used up will not extend the battery life, but will have a negative impact on the battery life. Answer: In fact, when charging lithium batteries, pay attention to eating less and more. Frequent shallow charging and discharging are more helpful to prolong its life. 3. Will overcharging cause the battery to explode? There are rumors that answering the phone while charging will cause the phone to explode. Experts said that this argument is untenable. If there is such a risk, the product will be set to charge without connecting a mobile phone. Solution: Lithium batteries generally have safety maintenance circuits and various safety equipment to ensure that the battery circuit is actively cut off in the case of excessive charging and discharging and short circuits. Therefore, unless there is a quality problem, the battery will not burst due to too long charging time. However, not pulling the plug after charging will fully charge the battery and accelerate the loss of battery capacity. In addition, for safety reasons, do not cover anything on the battery while charging, and do not put it on the bed to prevent fire. The correct way is to charge 1.3-4 hours. The charging time should not be too long. It can be charged. If the time is too long, it will seriously affect the battery life and the risk of attack. 2. The first charging time is not long. The first charging time is not 12 hours. This is what the old NiMH batteries do. Today's batteries are lithium batteries or lithium polymer batteries. Failure to use the photoelectric to run out the phone will seriously affect the battery life. It is best not to use universal charge. The universal charge current is unstable and the quality is uneven. Try to use the original charger. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
