18650 battery 3500mah lithium

　　What are the characteristics of 18650 battery 3500mah lithium?

　　1. The operating voltage of a single rechargeable battery is very high, which is three times that of nickel-cadmium batteries, three times that of nickel-metal hydride batteries, and nearly twice that of lead-acid batteries. This is the main reason for the high energy density of lithium-ion batteries. Therefore, when lithium-powered lithium batteries have the same working voltage, their series connection frequency will be much less than lead-acid batteries and nickel-metal hydride rechargeable batteries.

　　2. Light weight and high energy density, reaching 150Wh/Kg, which is twice that of nickel-metal hydride rechargeable batteries and lead-acid batteries, and four times that of lead-acid batteries. Therefore, the net weight is 1/3- of lead-acid batteries with the same energy. 1/4. From this perspective, lithium batteries consume less resources, and because lithium manganese oxide batteries use a large number of elements, compared to lead-acid batteries, the price of nickel-metal hydride rechargeable batteries is lower. The price of lithium-powered lithium batteries is even lower.

　　3. Small size, with a maximum power of 400Wh/L, and a capacity of one-half to one-third that of a lead-acid battery. Provide design conditions, design space and probability, the structure is more effective, and the appearance is more beautiful. At present, due to the limitations of the volume and weight of lead-acid batteries, designers' design concepts are greatly restricted. As a result, the structure and appearance of electric vehicles are clearly the same as those of thousands of other vehicles, similar and simple.

　　4. The cycle time is long and can be cycled up to 1,000 times. When the lithium battery pack capacity is maintained at 60%, the 100% battery charging cycle frequency can exceed 600 times, the service life can reach 3-5 years, and the service life is about 2-3 times that of lead-acid batteries. With the development of high-tech and the improvement of machinery and equipment, the service life of rechargeable batteries will be longer and the price-performance ratio will be higher.

　　5. The life of lithium battery is low, less than 5% per month.

　　6. The allowable operating temperature range is wide and the ultra-low temperature characteristics are excellent. The operating temperature of lithium-powered lithium batteries is -20℃~+55℃, which is especially suitable for ultra-low temperature applications. However, water-soluble rechargeable batteries (such as lead-acid batteries and nickel-metal hydride rechargeable batteries) operate at ultra-low temperatures. At this time, due to the change in fluidity of the lithium battery electrolyte, its characteristics are greatly reduced.

　　7. There is no memory, so there is no need to charge and discharge before each charge like nickel-cadmium batteries and nickel-metal hydride batteries, and you can charge it at any time. The battery of the lithium battery pack is charged deeply, which has little impact on the service life of the lithium battery pack. It can be fully charged and fully discharged. Our cycle test is full charge and full discharge.
