The 18650 lithium battery, what is the 18650 lithium battery?

The 18650 lithium battery is a cylindrical type, measuring 18mm in diameter and 65.0mm in height, with a rated voltage of 3.7V. In response to the demand for more powerful devices, the 18650 lithium battery pack was developed. 18650 manufacture By combining multiple 18650 batteries in series or parallel, a higher voltage and longer discharge time can be achieved. Compared to lithium cobalt acid batteries, which have a lower safety factor, the ternary material used in 18650 lithium batteries offers increased safety. However, due to its lower working voltage, it may not provide sufficient power for devices such as mobile phones (which typically have specific cut-off voltages). As a result, this type of battery is currently widely utilized in the market for other purposes.

The difference between an 18650 lithium battery and a ternary lithium battery

The ternary lithium battery has a large capacity of 18,650 lithium batteries, and the ternary lithium polymer can even reach 10,000 MA.

18650 lithium battery life is very long, the longer its life, the special development of lithium ion through the structure, the full charge is about twice or even more than the ordinary user charging system battery, it can be said that the capacity is very large.

It has no memory. It is likely to be difficult to charge and discharge the remaining charge before recharging this battery, which makes it more convenient to use; unlike nickel metal hydride batteries, nickel metal hydride batteries have a memory effect of discharge.

18650 lithium battery internal resistance is small, the volume damage is irreversible, can greatly reduce the functional loss of the rechargeable battery, improve battery life;

This lithium-ion battery is extremely safe and does not cause explosions or air pollution. The test results show that the probability of short circuit failure is reduced in most cases. Avoid overcharging or power outages.

How are 18650 batteries used?

The international economic market has recognized the 18650 lithium battery as a highly stable and valuable product. It has also been acknowledged as a leading technology among other lithium-ion battery products in the enterprise. This powerful battery is widely utilized in various industries, such as consumer digital technology, electronic information equipment, mechanical production equipment, and medical security machinery. Its applications range from service management robots and AGV trucks to unmanned aircraft and electric vehicles, making it a popular choice in society. Furthermore, it has shown great potential for development in smart phones, tablets, notebooks, electric toy cars, MP3/MP4 devices, mobile phone headsets, chargers, model aircrafts, and even mobile network telephone systems.

Characteristics of 18650 lithium batteries

Because of technical reasons, its early rated voltage and application field are both limited. However, its volume and safety balance coefficient are better than ordinary raw materials. As a result of the gradual improvement of the formula and structure, the battery's nominal voltage has reached, and its capacity has surpassed or even exceeded that of lithium cobalt batteries. The majority of people now prefer 18650 lithium battery packs.

Precautions for battery use:

On the first charge, avoid overcharging

It is easiest to control the charging time during the day, so you should pay attention to the time when charging the battery for the first time. Charging at night can easily cause overcharging and damage the battery.

Time required for charging.

Charge the 18650 lithium battery during the day, don't charge it at night. Noting the time of the charger can also allow danger to come, have time to deal with it.

Overcharging should be avoided.

Overcharging will shorten the life of the 18650 lithium-ion battery, and can also result in negative voltage. You should keep the charging time of the charger under 8 hours.
