Jinchaowei battery is made of Ni-MH material, which is mainly composed of positive and negative electrodes, diaphragm and electrolyte. The electrolyte is mainly liquid, and the main component is potassium hydroxide. Wei Chao black gold battery is made of alkaline Zn-Mn alloy with potassium hydroxide as electrolyte.

Gold battery is suitable for small current discharge, and can be used in calculators, remote controllers, quartz clocks, telephone landlines, etc. Wei Chao black gold battery is suitable for high current continuous discharge, and can be used for battery cars, electric cars, car backup batteries, etc.

Matters needing attention in the use of Wei Chao black gold battery

In the past, the motor power of electric vehicles was generally between 350 and 500 W, with low power consumption. However, in recent years, the demand of users has gradually increased. In order to cater to users' constant pursuit of high speed, manufacturers have designed more and more motor power, and even electric vehicles equipped with 1200W motors are common in streets and alleys. Although the speed of electric vehicles has increased, the loss of batteries has also increased, which also reduces the durability of batteries.

In the past, the batteries of electric vehicles contained cadmium, so their power and battery life were better. However, in recent years, in order to protect the environment, the battery of electric vehicles has adopted a cadmium-free design. This directly leads to the linear decrease of the conductivity of the battery, resulting in the problem of durability.
