Why is the life of lead-acid batteries shorter and shorter?

Let’s look at a real test first: a well-known battery brand launched a battery product equipped with a special charger. After one year of real market feedback, it was found that there was no battery product with a special charger or a battery product with a special charger. , The return ratio is equivalent to 20:1. Through testing, if the charger current does not reach more than 3A, then when the internal chemical reaction occurs in the battery charging process, not only will it release additional heat, but also increase with time and life cycle (the number of charging and discharging) , It will also produce some solid, liquid or gaseous by-products, in which solid impurities will crystallize on the reaction surface of the battery and cover the 'reaction sites' that can be used to store charges. The internalized battery has higher requirements for charging than the externalized battery. If the charger is difficult to meet the charging demand, then with each charge of the chemical reaction, it will not take long for more and more impurities to accumulate in the battery, which will lead to failure. Normal use. Many of the current chargers on the market are unable to meet the charging needs of the battery. In addition, many consumers do not have the common sense of maintaining the battery. As a result, the internalization of the battery is generally poor in quality and has become the norm in the current market. In addition, industry insiders believe that these reasons are: 1. Thinning of the electrode plate 2. Irregular charging 3. No longer using cadmium 4.
