18650 lithium batteries generally have the advantages of large capacity, long life, high safety performance, and wide range of use. No matter which manufacturer's
18650 lithium battery is the same in appearance size, the difference is the maximum capacity and maximum energy density ratio that can be achieved. When buying the 18650 battery, it is generally necessary to understand from its brand, capacity, current, voltage, and work temperature, and then select the 18650 battery that is suitable for.
1. Electricity equipment
According to the requirements of the electrical appliances, choose the applicable battery type and specification size, and purchase a suitable battery for electrical appliances according to the size and characteristics of the electrical power consumption.
2. Battery brand
Currently more reliable is Panasonic/Sanyo, Sony, Samsung, LG and other well -known global brands. Panasonic and Sanyo are capacity battery manufacturers. LG, Sony, Samsung power type 18650 is better.
3. Nominal capacity
The nominal capacity of the 18650 battery is related to endurance. The unit is "MAH". The higher the capacity, the stronger the endurance.
For example, a 2800mAh battery can continue to discharge for 2 hours with a 1.4A current.
4. Charging and discharge multiplier
Charging and discharge multiplied rate = charging and discharge current (A)/rated capacity (AH)
Charging and discharge multiplied rate refers to the current value required for the battery when it releases its rated capacity within the specified time. The unit of battery discharge rate is generally C (abbreviation of C -Rate), such as 0.5c, 1c, 5C, etc.
5. Battery resistance
The internal resistance is the resistance of the battery itself. The smaller the internal resistance, the less consumption, the stronger the discharge capacity. The internal resistance will generally write the battery introduction page. When buying Buy a battery of more than 100MΩ.
6. Work temperature
Temperature is a major factors that affect the life of the 18650
lithium battery. The higher the temperature of the lithium battery, the higher the speed of the lithium battery, and the higher the temperature, the greater the damage inside the lithium battery.
7. Pipanus and flat head
The so -called pointed and peaceful heads are designed by various manufacturers according to their own assembly needs, battery safety, battery capacity and other factors. There is no difference in essence.
8. Course and no protective board
The protective board is a few mm higher than the 18650 lithium battery without a protective board, and the price is slightly more expensive, but the safety is higher.
The 18650 lithium battery with a protective board can prevent the battery from being placed (after the release, it will cause the lithium battery to heat up, or even burn and explode).
Guangzhou Battsys Co., Ltd (NEEQ:837375), was founded in 2006, which is a join-stock high-tech enterprise engaging in ODM and OEM , specially for customized and diverse research&production of lithium-ion battery，BATTSYS annual production capacity is tens of millions battery cells. The products are exported to dozens of countries & regions such as Europe, America & Asia etc.
