Common sense to buy mobile phone battery 1. difference nickel cadmium, nickel metal hydride rechargeable treasure manufacturer of lithium-ion batteries: 1, see identification. Generally marked on the battery is English identity. NI-CD nickel-cadmium batteries NI-HI nickel metal batteries NI-LI lithium ion battery. 2, compare weight. Same capacity nickel-cadmium batteries, nickel metal hydride batteries, lithium-ion batteries nickel-cadmium batteries compare heaviest, followed by nickel-metal hydride, lithium-ion battery lightest. 2. The advantages and disadvantages of nickel-cadmium batteries: Ni-Cd battery is composed of two plates, one is made of nickel, cadmium and the other is made of two metals reversible reaction in the battery, so the battery can be recharged. Nickel-cadmium is characterized by "strong", and cheaper prices. Disadvantages are: cadmium metal pollution for the environment, small battery capacity, short life, so most low-grade nickel-cadmium batteries are batteries. Memory effect. Each charge will need a permit discharge, then recharge. 3. nickel-metal hydride batteries and disadvantages: nickel metal hydride batteries and nickel hydrogen ion synthesis, since it does not contain cadmium metal charge treasure molipow, will not pollute the environment, which is also known as "green batteries." NiMH battery power reserve 30% more than the nickel-cadmium batteries, mobile phone talk time is thus prolonged by 30%. NiMH batteries are lighter than nickel-cadmium batteries, longer service life. And environmental pollution, no memory effect. NiMH batteries drawback is the price more expensive than nickel-cadmium batteries, performance is worse than lithium. Mid-range battery. The advantages and disadvantages of the lithium ion battery: lithium-ion high-energy density as a battery material. Lithium-ion battery is a smart battery, it can be exchanged with the original dedicated smart charger, charging time to achieve the minimum and maximum life cycle and large capacity. Lithium ion batteries are currently the best performance of the battery. Compared with the same size nickel-cadmium batteries, nickel metal hydride batteries, power reserve largest, lightest, longest life expectancy, the shortest charge time, no memory effect. But the most expensive on the charger is also selective. Now a lot of profiteers in order to reap huge profits, often using class C or assembly phone posing renovated Class A parallel phone sales. As a huge price difference between the face and the regular routine of consumers, they can not tell whether you want to buy a mobile phone vendors like to say that excellent quality, at the seller's glib only to see his wallet "diet." But this type of renovation or assembled parallel phone often in order to reduce costs, it is also often used in parts of substandard products, even shoddy products also conceivable product assembled by such good quality phones can actually go there. Currently often see reports of mobile phone battery exploded wounding event, the reason is consumers buy these assembled parallel phone. And not only this type of mobile phone hardware problems, including software phone use. Due to the parallel assembly hardware specifications can not guarantee that the product and the original field is consistent charging treasure a generation of fat, software, mobile phones and mobile phone use can also cause a hardware conflict. Frequent crashes is commonplace, and some even cause frequent phone book is lost, unable to contact friends. A generation of fat _ charging treasure large can (certified) _ charging treasure provided by Shenzhen Shuo New Energy Co., Ltd. Shenzhen Shuo New Energy Co., Ltd. (www.molipow.com/page-about.html) Guangdong Shenzhen, a leader in mobile phone battery, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In the master to lead the staff warmly welcome all inquiries negotiations to create a better future can master.
