Distinguishing the quality of 18650 lithium batteries from three aspects.

Distinguishing the quality of 18650 lithium batteries from three aspects.

LED flashlights generally use 18650 lithium batteries, which have become mainstream. However, the number of fake explosion-proof flashlight batteries on the market is generally divided into several categories:

1. False capacity
At present, China's 18650 battery technology has a capacity of 2200, and many sellers, in order to attract consumers, falsely claim that the bottom capacity battery has a capacity of 3000 or 3200, deceiving consumers and seeking more benefits.

2. Refurbish batteries
Refurbished batteries come from dismantled batteries abroad, obtained through illegal channels, and then refurbished with false capacity. These batteries are very dangerous, and consumers carry a timed explosive with them. Please keep your eyes open when consuming.

3. Counterfeit batteries
The words' shanzhai 'are familiar to everyone. Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. The chemical properties of lithium metal are very active, making the processing, storage, and use of lithium metal highly environmentally demanding.
