What is an 18650 lithium battery and how to distinguish a good quality 18650 lithium battery

What is 18650 battery? As a representative of cylindrical lithium batteries, 18650 lithium batteries have always been concerned and valued by all lithium battery manufacturers. What is 18650 lithium battery? What are the 18650 lithium batteries? Definition of 18650 battery: 18650 lithium battery number 18650 represents the external specifications: 18 represents a diameter of 18mm, 65 represents a length of 65mm, and 0 represents a cylindrical battery. It is a standard lithium-ion battery type set by SONY in Japan to save costs, and is called 18650 lithium battery. Flat-top and pointed 18650 lithium battery Flat-head 18650 lithium battery: without BMS protection board. Pointed 18650 lithium battery: There is a difference between the atmosphere with a protective plate and without a protective plate. The length of the protective plate will be 2mm longer than that without the protective plate. Under normal circumstances, the protective plate with or without the protective plate depends on whether the equipment used has integrated battery protection circuit . When used on some special equipment, such as equipment that requires high current discharge, a battery without a protective plate may be required. The 18650 lithium battery is an industrial battery. It does not contain over-charge and over-discharge protection. Lithium batteries are prone to over-discharge during operation. These conditions can cause damage or permanent failure of lithium batteries. Therefore, whether it is a single 18650 lithium battery or an 18650 battery pack product, it must be equipped with a protection circuit. How to choose a high-quality 18650 battery? The 18650 lithium battery is different from other standard batteries. Different brands have different quality levels, and different brands have their own core competitiveness. This is why we say that it is best to choose the 18650 lithium battery that is most suitable for us. Therefore, when buying 18650 batteries, we should consider the following factors: 1, brand 2, capacity 3, voltage 4, continuous discharge rate 5, chemical nature 6, battery Life 7, how to avoid buying fake 18650 lithium battery with safety function? When we buy 18650 lithium batteries, we will inevitably encounter many fakes in the market. How should we avoid buying fake and shoddy products? The following points should be noted: 1. Battery maintenance 2. Battery packaging 3. The well-known brand and model of the battery tester 18650 lithium battery cell: 1.
