CR2320 battery.This is the real reason why electric vehicle batteries are becoming increasingly less durable

　　Many people have reported to me that batteries are becoming increasingly less durable. Previously, they had a normal lifespan of two and a half to three years of use. Why is it that from these two years on, the battery of electric vehicles has been used for one and a half to two years and cannot run far, is no longer durable, and this lifespan is no longer usable?

　　Some people just don't understand. Is this battery of poor quality, or is the manufacturer adding fewer elements and the lifespan not as long as before, or is it using recycled lead?

　　Today, let's share our experience in repairing and take a look together.

　　01. Which types of batteries are commonly used in the market

　　In recent years, the most commonly used batteries in the market are types such as Super Wei, Tianneng, Jingqiu, Xupai, and Haibao.

　　There are also circulating batteries such as Lipon, Nandu, Wanhao Wanjia, Yaheng, Xingheng, Panasonic, Jinri Super, etc.

　　The battery brands with high popularity and high sales in each region of the country are not the same. From the overall data of the country, the first category has the highest sales. After all, these battery brands have been on the market for a relatively long time, have a wide reputation, have many recognized people, and rank first in terms of sales volume.

　　02. What are the reasons why batteries are not durable

　　We have discovered a problem that whether the batteries used in the original car or those replaced in other stores are no longer as durable as before, which is a crucial factor.

　　There are several reasons for the shortened service life of batteries: one is that there are changes in the internal raw materials of batteries, and lead-acid batteries do not allow the addition of cadmium.

　　Not adding cadmium can lead to a decrease in the service life and stability of lead-acid batteries, but cadmium can cause serious environmental pollution and is an element that needs strict restrictions.

　　As early as 2012, the Ministry of Industry and Information Technology, the Ministry of Environmental Protection, and industry associations established the "Entry Conditions for the Lead Battery Industry", which clearly stipulated that the production capacity of lead batteries and their lead-containing components with cadmium content higher than 0.002% or arsenic content higher than 0.1% should be phased out before December 31, 2013. All battery companies strictly comply with national regulations. Batteries produced after 2014 comply with national standards and strictly control the cadmium and arsenic content in batteries. Some companies even introduce batteries completely free of cadmium and arsenic.
