What is the most intuitive price of 18650 lithium-ion batteries currently on the market?

Introduction What is the most intuitive price of 18650 lithium-ion batteries currently on the market? The lithium battery model, such as 18650, refers to the battery size, with a diameter of 18mm and a length of 650mm.

What is the most intuitive price of 18650 lithium-ion batteries currently on the market?

Lithium battery models such as 18650 refer to the battery size, with a diameter of 18mm and a length of 650mm. Generally, the larger the battery, the greater the capacity.

The general capacity of 18650 is around 2000 mAH.

The output current of lithium batteries is relatively large and can be discharged with a current greater than 2C, 2000 mAh is 4 amps

In addition, some lithium batteries used for current power supply have a discharge current of up to 10C. It can be used on battery cars, power tools and other equipment requiring strong power.

The current market price of 18650 is about 12 yuan. The price is also different with or without a skid plate. Generally, the length of the lithium battery with a protective plate is 670mm.

Note: When using a battery in bedhium, a protection plate must be connected. Otherwise. , overdischarge and overcharge will cause fatal damage to the lithium battery, especially overdischarge

What is the difference between 18650 battery and general lithium battery

Since the size of 18650. the battery is fixed, "18" represents the diameter, "65" represents the height, "0" means the cylindrical shape. The maximum milliamp-hour capacity of the 18650 lithium battery is always a question worthy of discussion. This is why it has always attracted the attention of many practitioners. In recent years, various Chinese manufacturers have improved their technology and continued experimental research and development. The capacity has also gradually increased. The lab was able to produce 18650 batteries with a capacity of more than 3,500 mAh. However, stability and consistency are not enough and mass productionhas not yet been established. If someone says someone has 3500 or 4000 mAh it's a lie, you'll know just by looking at the price. The large capacity 18650 lithium battery currently purchased in bulk on the market is 2950 mAh. Batteries of this capacity are also called 3000 mAh by others. At present, batteries with a capacity between 2200 mAh and 2600 mAh are relatively stable, and all aspects of technology are relatively mature. If you are making a battery, it is best not to use high capacity batteries. This is not cost-effective in terms of cost-performance or battery life after assembly. Therefore, the higher the battery capacity. the more unstable it will be.

Batteries need to be customized according to different products used in different working environments and fields. If the product is mid to highrange, the battery can choose imported batteries from major brands such as Sanyo, Panasonic, etc. There are also many domestic batteries produced by small-scale battery cell manufacturers. If you are too price sensitive, you can choose batteries with a capacity of 1800 mAh to 2600 mAh produced by mainstream domestic manufacturers such as BYD. and Dongguan Hongwei Energy. Most application areas have different current and time requirements, which is why most power banks are presented as batteries. When choosing a battery, you need to consider the consistency, stability and safety of the cells, as well as each group of cells. The battery in the battery must match in all respects, such as the same voltage, the same internal resistance, the same capacity, etc. These indicators are very important.

1. The battery capacityst different, 18650 battery.The capacity of the battery is generally between 1200 mAh and 3600 mAh, while the capacity of the general lithium battery of the same volume is about 800 mAh;

2. Lifespan; of the battery is different. The lifespan of 18650 batteries can reach more than 500 times under normal use. Generally, the life of lithium batteries under normal use is about half that of 18650 batteries; /p>

3. The safety performance of batteries is different. The 18650 lithium battery has high safety performance, does not explode, is non-toxic and non-polluting. Generally, lithium batteries are at risk of exploding when exposed to high temperatures. temperatures or improper use, and the materials inside general lithium batteries have a high capacity to pollute the environment;

4. The discharge voltagerge of batteries is different from the discharge voltage of 18650. lithium battery is generally 3.6 volts, 3.8 volts and 4.2 volts. The general lithium battery discharge voltage is about 3.0 volts.
