the phenomenon that the active material on the battery plates are gradually turned into lead sulfate with coarse and hard crystals full of plate surface due to deep discharge (too much) or long-term insufficient charge, which will block the plates micropore and hinder the electrolyte penetration and conduction current, thus the battery charging and discharging performance is extremely deteriorated, and the actual capacity is seriously insufficient; and it could not be reduced to lead dioxide and spongy lead by conventional charging methods.

Lead acid battery is mainly composed of positive/negative plate group, separator, battery container, electrolyte, battery cover, etc. The electrode is mainly made of lead and lead oxide, and the electrolyte is sulfuric acid solution.

Do you know how to group the batteries? Do you know how to calculate the driving mileage of electric vehicles batteries? Do you know how to add repair fluid to the battery? If you don't know, you must read this article.

However, the above phenomenon is not common, and most chargers will not or do not often have similar problems. This kind of charger is not only rare, but also a relatively old one that has been used for many years. The correct way to use the charger is that at the later stage of charging, although most of it has been charged, a small amount of sulfurized substances on the plate are not completely reduced.

If battery overheating is caused by excessive discharge current, there may be the following reasons:

According to WHO statistics, a quarter of adults worldwide are not physically exercising enough. The latest WHO physical exercise guidelines recommend that all adults over 18 years old, including those with chronic medical conditions or disabilities, should engage in at least 150 to 300 minutes of moderate-to-vigorous aerobic exercise per week, even if they are over the age of 60.

Power batteries include lithium-ion power batteries, metal hydride/nickel power batteries, etc. Lithium-ion power batteries are usually referred to as lithium-ion batteries. Lithium-ion batteries are an important category of power lithium batteries for new energy vehicles and have the largest market share.

Sometimes, my friend will ask me a question: my car's battery has been used for 3 to 4 years, except for the dust in the corner, the appearance looks good, it is almost new. But all of a sudden it broke down. What happened?

What are the differences between power lithium batteries and ordinary 18650 lithium batteries?

The battery is the core component of an electric vehicle. The quality of the battery directly determines its lifespan and mileage, but some batteries are "killed" in advance due to improper installation.

On April 19th, 2022, Better Technology Group Limted (hereinafter referred to as "Better Group") ISO Quality Management System Launch Conference was successfully held. The full participation in this meeting means the full launch of ISO quality management system project in Better Group , is another very important milestone in the company's development process.

On April 14, 2022, the first stop of "Better Learning Communicty", the president of the company Ms. Wei personally led some middle and senior managers to go to Xiamen Justsun Group to exchange and study, and received the warm reception from Mr. Shao and Mr. Gan of Justsun Group .
