Why is the battery life getting shorter and shorter?

I often hear feedback from people around me that the quality of the battery in recent years is not as good as before, especially in winter, it is even less durable. The quality of the battery has always been controversial.

Why are batteries generally not as good today as they used to be? 

Many dealers and repairers will find that when they test batteries, many batteries that have been used for less than half a year only have a discharge time of 20 minutes.

Let’s look at a real test first: a well-known battery brand has launched a battery product equipped with a special charger. After a year of real market feedback, it is found that for the batteries without a special charger and the batteries with a special charger, the repair ratio is equal to 20:1

From the test we can find that, if the charger current does not reach more than 3 amps, then when the chemical reaction occurs during the charging process of battery formation, it will not only release additional heat, but also produce some solid, liquid or gaseous. And the solid impurities crystallize on the reaction surface of the battery, obscure the "reaction sites" that can be used to store electric charge with the increase of the time and cycle life. (charge and discharge times)

Battery formation batteries have higher requirements for charging than plate formation batteries. If it is difficult for the charger to meet the charging requirements, then with the chemical reaction of each charging, it will not take long for more and more impurities to accumulate inside the battery, which will lead to malfunction.

Many chargers on the market today are difficult to meet the charging needs of batteries. In addition, many consumers do not have the common sense to maintain batteries. As a result, the general poor quality of battery formation batteries has become the norm in the current market.

In addition, there are industry experts who believe that the reasons are:

1. The battery plate become thinner nowadays

2. Improper charging

3. Stop using cadmium

4. The increasing work power of electric motorcycles

Besides, what other reasons do you think? Comments are welcome!

Finally, I would like to remind everyone: When buying batteries, you must find formal merchants to prevent encountering batteries refurbished by black-hearted merchants. In addition, in daily use of batteries, you must charge them correctly and pay attention to battery maintenance.
