     There are already commercialized rechargeable batteries, nickel cadmium batteries, nickel cadmium batteries, nickel iron batteries, lithium ion batteries, etc.. What are the cheap batteries for cars? How to choose cheap batteries for cars?


     Lead acid battery is the oldest battery, the technology has been very mature, low cost, can be a large current discharge, is the standard configuration of the current car battery. But its fatal flaw is the life is short, the cycle life is generally not more than 500 times, and will cause the serious pollution to the environment. its application has been more and more restricted, western developed countries have banned the production and use of lead-acid battery. Is not suitable for the cheap batteries for cars.

     The nickel cadmium battery technology is mature, with good cycle life, charge and discharge can be repeated more than 500 times; low cost; and can large current discharge, has high safety, can be used in electric vehicles; but after repeated several times to maintain battery charge and discharge in low capacity, the "memory effect" lead to a reduction in battery capacity, and nickel cadmium batteries on the environment pollution is serious, at present in Europe and the United States national ban on the production and use. Is not suitable for the cheap batteries for cars.


     Nickel iron batteries and nickel cadmium battery performance, the two can almost replace each other, but in the large current discharge performance is less than the cadmium nickel battery, but no memory effect, and the cost is lower, completely green. The most commendable is its high security, has never been a security incident, will not cause pollution to the environment; has a long service life, and thus get the special favor of European and American users. Suitable for the cheap batteries for cars.


     Lithium ion battery is the most popular battery, with the characteristics of high voltage, high capacity, green environmental protection, widely used in mobile phones, laptops and other digital products, can be a large current discharge, is currently the most popular battery electric vehicles. But its cost is high, more than three times the cadmium nickel battery; the security is poor, easy to explode, from time to time to see the report of the lithium ion battery explosion.


     In summary, the iron nickel battery is an ideal choice for electric vehicle battery.
