How to buy a 26650 lithium battery?

26650 lithium batteries are widely used in electric tools, lighting, landscape energy storage, electric vehicles, toys, instruments, UPS backup power, communication equipment, medical equipment and lighting fields. What should we pay attention to when we buy 26650 lithium batteries?

1. Appearance and production technology

Looking at the appearance refers to the appearance, workmanship, size and process of 26650 lithium batteries. The advanced craftsmanship is very comfortable. After polishing, the rubber oil polishing material is both well -felt, and at the same time, the insulation performance is also very strong.

2. Capacity identification

The 26650 lithium battery without a clear labeling capacity is likely to be a junk battery that uses inferior battery cores or recycling battery cores. There are many cheap 26650 lithium batteries on the market. It is made of recycling battery core or disassembly battery core. Although the price is cheap, the life span is short, the quality is unstable, and the equipment may be damaged by accidental use.

3. Whether there is a protective board

The characteristics of the 26650 lithium battery determine that the 26650 lithium battery must be added with a protective board to prevent the occurrence of 26650 lithium batteries, over -loading, and short circuit. Danger. Under the fierce price competition, the battery packaging factories seek a lower price protection circuit, or the device is omitted at all, making the market full of 26650 lithium batteries with explosive hazards.

4. Flat head and pointed
26650 lithium batteries are divided into flat heads and pointed heads. The difference between the two is a protective board and one without a protective board.
Flat 26650 lithium battery: without protective board.
Sipper 26650 lithium battery: with a protective board, because the top of the protective board is protruding, the prominent part is the protective board.
Under normal circumstances, I recommend buying pointed batteries to ensure more compatibility equipment and use. The positive and negative poles of electrical appliances are usually designed with spring, which can be used for scalability.

However, if the flat -headed battery is used to connect, the positive pole of the flat head cannot be exposed to the negative electrode of another battery.
