Now a lot of lithium battery manufacturer had mastered the battery assembly technology and lead and cadmium plate, as long as the regular production of strict management to produce the battery cycle life won't be poor. Small power motors such as lead calcium technology in 36 v180w life really is very long, but now in the market of 350 w and 500 w motor to lead calcium battery is killer, because lead calcium batteries and they were afraid to large current, consumers in the choose and buy electric vehicles in the process of what problem should pay attention to the battery?
　　1, the choice under the same quality and low price. Refers to the same quality manufacturers plate production ability or have the good choice plate capacity, good production management, has the ability to produce high quality products. Electric vehicle battery manufacturing process complex conditions of use harsh, any brand will have a 3-5% rate of return, who preached his battery not how bad it must be to brag. Focus on indicators, such as electric capacity and the voltage of the battery. Battery electric vehicle's main source of power, different electric capacity, power and range of electric vehicle vary in price from 2 to 3 times. When buy, therefore, to understand what to buy electric vehicle battery how much, how many ampere. Under normal circumstances, 48 v 20 more than 36 v battery 10, after a full charge of disposable driving distance, in general, the battery capacity, the greater the power, the higher the price accordingly.
　　2, select normal manufacturer and powerful businessman. Lithium battery electric tools factory closure operating businesses closed every year is not a few. To ask clear electric car warranty with warranty specific content. Businesses generally promised battery warranty for a year, but the businessman said bao "year" is a period of time the: generally refers to the date of purchase, quality problems replacement battery within six months, six months to a year to replace the old battery maintenance, after a year of use is not responsible for the problems the businessman. Accordingly, when consumer is buying storage battery to and merchants to negotiate good battery warranty period and the corresponding specific content, make clear on the warranty card, lest produce consumer disputes.
　　3, good after-sales service, to understand the battery. Because of the particularity of the lithium battery power tools, so good after-sales service and technical support is the key to ensure the normal order of the battery use. To choose the brand, service and reputation. Brand, service and word of mouth is the best way to promote electric car batteries. When consumer choose and buy should not only choose the good quality electric vehicle batteries, than the service, than the brand at the same time, pay attention to know whether the products in the region have after-sales service points, in terms of quality and credibility of service reputation, so that the future electric car battery failure, can be resolved in the shortest possible time.
