Nickel cadmium/nickel cadmium battery
Nickel-cadmium battery is used for low-grade charging electric push boat. Nickel-cadmium battery is economical and durable, but it has memory effect, so the battery capacity will decrease a little after one charge. At present, the capacity of nickel-cadmium batteries used in electric clippers in China is mostly below 800 mA, and the service life of batteries used in barbershops is less than one year. At the same time, nickel-cadmium batteries are toxic and not environmentally friendly.
nickel-hydrogen battery
Mid-range rechargeable electric clipper uses Ni-MH battery, and the power reserve of Ni-MH battery is 30% more than that of Ni-Cd battery. The rechargeable electric clippers produced by regular factories generally use Ni-MH batteries with a capacity of more than 1200mA, which has no pollution to the environment. However, the self-discharge effect of Ni-MH battery is high, about 30% per month. If it is not used frequently, it needs to be charged before each use.
lithium battery
World brands such as Wall in the United States, Mo Ze in Germany and Matsushita in Japan have long used lithium batteries. In recent years, due to the decline in the production cost of lithium batteries, many domestic rechargeable electric scissors have gradually begun to be used. At present, rechargeable electric scissors using lithium batteries are the best. But even the best professional rechargeable electric hair clipper will not last more than 5 years.
motive power
Due to the limitation of battery capacity and cost, the greater the power, the shorter the use time. Therefore, the power of rechargeable electric hair clipper is generally below 5W, and the power of some infants' hair clipper is even less than 3W, which is easy to cause unsmooth shaving and haircut. However, the power of general plug-in electric clippers is above 6W, and it has simple structure and long service life. For home users with low haircut frequency, plug-in hair clippers with wires are a better choice.
