The advantages of 18650 lithium-ion batteries mainly include the following aspects:
1. High energy density: 18650 lithium-ion battery has high energy density, which can store more energy in the same volume than other types of batteries.
2. Long life: 18650 lithium-ion batteries have a long life, and can generally be charged and discharged hundreds or more times, which is longer than other rechargeable batteries such as nickel-metal hydride batteries and nickel-cadmium batteries.

3. Low self-discharge rate: 18650 lithium-ion battery has a low self-discharge rate, and the power loss is small when stored for a long time.
4. High discharge current: 18650 lithium-ion battery has a high discharge current, which can support the use of high-power equipment.
5. High charging efficiency: 18650 lithium-ion battery has high charging efficiency and can be fully charged in a short time.
In short, 18650 lithium-ion batteries have the advantages of high energy density, long life, low self-discharge rate, high discharge current and high charging efficiency, so they are widely used in electronic equipment, power tools, electric vehicles and other fields.

Therefore, I recommend TEFOO ENERGY standard lithium battery, which is convenient for operators to carry out mobile indoor and outdoor operations. Providing continuous, efficient and stable mobile power supply has become the greatest guarantee for the normal operation of such equipment. The solution uses high-performance batteries, so that the entire battery has the characteristics of high energy ratio, light weight, small size, high cycle life, high safety, and high consistency. The battery is very convenient to use, and the original battery can be directly replaced on site.
