What is a storage battery? Battery is a device that converts chemical energy directly into electric energy. It is a rechargeable battery designed by reversible chemical reaction to achieve recharging. It usually refers to lead-acid battery, which belongs to the secondary battery. When charging, the external electric energy is used to regenerate the internal active substances, and the electric energy is stored as chemical energy, which is converted into electrical energy output again when it needs to be discharged, just like the common mobile phone battery in life.

     When it comes to batteries, everyone immediately thinks of electric cars. How far an electric car can go depends mainly on how much energy its battery can store. For just bought a new electric car, it must run fast, but people who have electric cars will find that after riding an electric car for a period of time, you will obviously find that after charging the electric car once, the cycling time is significantly reduced. This is a common problem of the battery (time used for a long time, it will become difficult to save electric energy). At this time, people's first reaction is to change the battery, to extend the battery storage time of electric vehicles, so now there are a lot of sales of electric vehicle battery replacement.

     According to professional analysis, many of the "new batteries" we buy are actually wearing "new clothes" on the surface, which is a variety of assembly, or "across a number of races", which is that some businesses are selling batteries under the name of super long life. This kind of second-hand batteries "across the race", most of them will cause the unstable performance in the charging process, which will bury a hidden danger for safety.
     There are a lot of battery shoddy production phenomenon, protection plate simple, lack of fuses, and even the name of the product are misspelled, this situation will lead to unimaginable consequences. According to statistics, there were 6,462 fire incidents involving electric vehicles in the first half of this year, which caused very serious social security problems.
      Although almost every family has a car now, many people like to ride electric vehicles, which are used for short walking or short distance transportation. If the safety of batteries cannot be guaranteed, it will be very dangerous. This is to rely on the conscience of the business to grasp the scale to produce safe performance of the battery.
