1800mah 18650 battery.Advantages of lithium batteries

　　1. High energy. It has a high storage energy density, which has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries.

　　2, long service life, service life can reach more than 6 years, lithium ferrous phosphate as a positive battery 1C (100%DOD) charge and discharge, there can be 10,000 times of use records;

　　3, the rated voltage is high (single operating voltage is 3.7V or 3.2V), about equal to the series voltage of 3 nickel-cadmium or nickel-metal hydride rechargeable batteries, easy to form a battery power pack; The lithium battery can be adjusted to 3.0V through a new type of lithium battery regulator technology, which is suitable for the use of small electrical appliances;

　　4, with high power bearing capacity, among which the lithium ferrous phosphate lithium ion battery for electric vehicles can reach 15-30C charging and discharging capacity, which is convenient for high-strength start-up acceleration;

　　5, the self-discharge rate is very low, which is one of the most prominent advantages of the battery, generally can be less than 1%/ month, less than 1/20 of the nickel-metal hydride battery;

　　6, light weight, the weight of the same volume is about 1/6-1/5 of the lead acid product;

　　7, high and low temperature adaptability, can be used in the environment of -20℃ -60℃, after process treatment, can be used in the environment of -45℃;

　　8, green environmental protection, regardless of production, use and scrap, does not contain, does not produce any lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances.

　　9, the production basically does not consume water, for the lack of water in our country, very advantageous. Specific energy refers to the amount of energy per unit weight or volume. The specific energy is expressed in Wh/kg or Wh/L. Wh is a unit of energy, W is watt, h is hour; kg is kilogram (a unit of weight) and L is liter (a unit of volume).
