We are the main manufacturer of 18650 cylindrical battery in our country. Because our products are of good quality and excellent price, they have won unanimous praise from people inside and outside the industry. The High security 18650 battery and 18650 rechargeable lithium battery is our hot sale products. I will tell you something knowledge of them.
Common 18650 batteries are divided into lithium ion batteries and lithium iron phosphate batteries. The voltage of the lithium ion battery is 3.7v, the charging cut-off voltage is 4.2v, the nominal voltage of the lithium iron phosphate battery is 3.2v, the charging cut-off voltage is 3.6v, the capacity is usually 1200mah-3350mah, and the common capacity is 2200mah-2600mah.
Today, let’s talk about the 18650 cylindrical battery At first . There are many pieces advantages of its as follow :
First, the capacity of 18650 lithium battery with large capacity is generally between 1200 ma/h and 3600 ma/h, while the general battery capacity is only about 800mah. If it is combined into 18650 lithium battery pack, the 18650 lithium battery pack can break through 5000mah casually.
Second, long life 18650 lithium battery has a long service life, the cycle life can reach more than 500 times during normal use, which is more than twice that of ordinary batteries.
Third, high safety performance 18650 lithium battery has high safety performance, does not explode, does not burn; Non-toxic, pollution-free, ROHS trademark certification; All kinds of safety performance can be completed at one time, and the cycle times are more than 500 times. High temperature resistance, discharge efficiency up to 100% at 65 degrees. In order to prevent the short circuit of the battery, the anode and cathode of 18650 lithium battery are separated.
Fourth, the voltage of 18650 lithium batteries with high voltage is generally 3.6V, 3.8V and 4.2V, which is much higher than the voltage of 1.2V of nickel cadmium and nickel hydrogen batteries.
Fifth ,without memory effect, it is not necessary to empty the remaining power before charging, which is convenient to use.
Next, let us talk about the 18650 rechargeable lithium battery. Rechargeable batteries have a long service life and a cycle life of more than 1,000 times. Although the price is more expensive than dry batteries, it is still more cost-effective if used frequently. The capacity of rechargeable batteries is lower than that of alkaline batteries or zinc-carbon batteries of the same specification.
Our company’s high security 18650 battery is very safe and cheaper than others. It is very popular in our country, and many customers' feedback on it is also positive. And will sign a long-term contract with us .They will bring more new customers to buy our products
