Why are new batteries not as durable as old batteries?

In the daily driving process, few car owners will cherish the car. Basically, no matter what the terrain is, it will rush forward, so it is normal for the motor to get water and rust. After a long time of use, the demagnetization of the motor's magnetic steel and the wear of the bearing will cause the battery to supply more energy. Even a new battery will cause serious energy loss. 2. Controller Leakage If the controller leaks, the battery must be running out of power all the time, even if it is a new battery, it will not be able to run out of power all the time. Third, battery quality problems With the continuous upgrading of technology and raw materials, the phenomenon of battery quality degradation will only exist in small brands and miscellaneous brands, because these brands lack sufficient strength to support product upgrades. Regarding the first-tier brands, the battery quality is upgraded year by year. If the quality of the big brand battery you buy has a quality problem, then you have to verify whether you have bought a fake. 4. The electric vehicles used in the upgrade of accessories were mostly small motors, 350w, with small body and light weight. However, the current electric car motors all have 500w/800w/1000w, the body weight is heavier, and a variety of new ones are added to the car. Lights and speakers will also increase power consumption. Although this is not an important reason, it also has a certain impact.
