With the improvement of people's living standards, electronic products such as mobile phones, laptops, digital cameras and video cameras have gradually entered people's lives and work. In these high-tech consumer goods, whether it is from a technical point of view or price considerations, batteries occupy a very important position. Today, the majority of electronic products currently on the market, the batteries used have basically completed the transition from nickel batteries to lithium batteries. Therefore, knowing the knowledge of lithium batteries and mastering the correct use of lithium batteries is very necessary. So how to identify true and false lithium batteries? Under non-professional conditions, the following methods can be used: batteries of the same capacity, lithium batteries are lighter than nickel-metal hydride and nickel-cadmium batteries; battery charging with lithium battery charger If the battery is hot during charging, it is a nickel-hydrogen or nickel-cadmium battery. If there is no big change in temperature, it is a lithium battery. If the battery is short-circuited "instantaneously", if the battery is "no power", then Lithium batteries, if still "electric", are nickel-metal hydride and nickel-cadmium batteries. In addition, when you buy a battery, you should also pay attention to the following points: 1. “Capacityâ€: A battery with no clearly marked capacity (such as 1000mAh or 1000mA), it is likely to use a poor quality battery or a recycled battery. Although the price of the battery is cheap, the life is short and the quality is unstable. Inadvertent use may damage the electronic product! In addition, a lithium battery that is too light means that the battery capacity is insufficient. For example, the lithium battery labeled 900mAh weighs less than 30g. The battery is likely to have a problem! 2, "Standby time": In the mobile phone, the standby time is the continuous use time after the battery is loaded into the mobile phone to the next charge. Because of the unstable battery quality, the general commercially available battery cannot guarantee the standby time for the customer. 3, "safety protection circuit board": no protection circuit board, lithium battery may be deformed, leaking, explosion danger! 4, the voltage of a single lithium-ion battery is generally 3.6V or 3.7V, so if the charger shows For 5V, there must be a problem. In addition, after purchasing a good quality lithium battery, it needs to be used correctly to prolong the service life. In the use of lithium batteries should pay attention to: 1. How to charge the new battery? After the battery is placed for a period of time, it will enter the sleep state. At this time, the capacity is lower than the normal value, and the use time is also shortened. After 3 to 5 charges, the battery can be activated to restore normal capacity. Due to the characteristics of the lithium battery itself, it has almost no memory effect, so the new lithium battery does not require special methods and equipment during the activation process. Charging is best done in accordance with standard time and standard methods, especially for over 12 hours of extra long charging. 2. When should I start charging in normal use? According to the experimental table of charge and discharge cycle of lithium ion battery: cycle life (10%DOD): >1000 times, cycle life (100%DOD): >200 times (DOD: depth of discharge) English abbreviation). Therefore, the lithium battery is not suitable for over-discharge. It is better to charge the battery in time when there is a certain amount of power, so as to prevent the battery from being damaged due to excessive discharge and damage the battery. 3. When the battery is inadvertently short-circuited, the internal protection circuit of the lithium battery will cut off the power supply circuit to ensure the safety of the user. The battery can be recovered by re-charging it. It is best to buy lithium batteries. You should choose after-sales service, international and nationally recognized brand batteries. These batteries use high-quality raw materials, have perfect protection circuits, exquisite casing, wear-resistant, anti-counterfeit chips, and good cooperation with electronic products. , can achieve good communication results.
