Disadvantages of 18650 battery.

Defect

The biggest disadvantage of 18650 lithium batteries is that their volume is already fixed, making it difficult to locate them when installed in some laptops or products. Of course, this disadvantage can also be considered an advantage, as it is a disadvantage compared to other polymer lithium batteries that are customizable and variable in size. And compared to some products with specified battery specifications, it has become an advantage.

18650 lithium batteries are prone to short circuits or explosions, which is also relative to polymer lithium batteries. If compared to ordinary batteries, this disadvantage is not so obvious.

18650 lithium battery production requires protective circuits to prevent the battery from being overcharged and causing discharge. Of course, this is necessary for lithium batteries, which is also a common drawback of lithium batteries, because the materials used in lithium batteries are mostly lithium cobalt oxide materials, and lithium cobalt oxide materials in lithium batteries cannot discharge high currents and have poor safety.

The production conditions for 18650 lithium batteries require high standards. Compared to general battery production, 18650 lithium batteries require high production conditions, which undoubtedly increases production costs.
