3.7V lithium-ion batteries feature a stable nominal voltage of 3.7V, high energy density, low self-discharge rate, and long cycle life. They can be adapted to a variety of low-power to medium-low-power devices, with stable electrical characteristics and good environmental adaptability.
The 18650 lithium battery, as a typical representative of 3.7V lithium-ion batteries, in addition to having the above-mentioned common features, also has a cylindrical shape. Its standardized size facilitates unified design and installation. The capacity is usually between 1200 and 4000 mAh, and it has a relatively strong power output capacity. It performs excellently in devices such as high-intensity flashlights and laptop battery packs. Its mature production process and extensive market applications result in relatively good cost control and supply stability.
3.7V lithium-ion batteries exhibit excellent operating characteristics. Their nominal voltage of 3.7V is suitable for a wide range of low-power to medium-low-power devices, and the discharge cut-off limit effectively protects the batteries. There are various capacity specifications available, which can flexibly meet the energy requirements of different devices, showing stability in the relationship between capacity and usage time. They have relatively strong adaptability to the environment. The cycle life generally can reach two to three years and can be further extended with proper use. They are highly competitive in the field of energy supply for miniaturized and portable devices, providing reliable, efficient and long-lasting power solutions for numerous electronic products.
Lithium-ion batteries have a longer cycle life, usually ranging from two to three years.How long a 3.7V lithium-ion battery can be used depends on various factors:
Battery Capacity: The larger the capacity, for example, the common 2000mAh one will have a longer theoretical usage time than the 1000mAh one. However, the actual usage time will be shortened due to efficiency losses.
Power Consumption of Devices: Devices with low power consumption (such as electronic watches) consume electricity slowly, so they have a long usage time; while devices with high power consumption (such as small drones) consume electricity quickly, resulting in a short usage time.
Charge-Discharge Cycles: Generally, lithium-ion batteries can withstand a certain number of cycles. As the number of cycles increases, the battery capacity decays and the usage time shortens.
Environmental Factors: Both excessively high and low temperatures will affect the usage time, and high humidity can also cause damage.
