In more than usual attention to the appearance, but also when some abnormal Please do not use, replace it immediately charge treasure, not hurt it, the throw to throw charge treasure investment, there is a dark phenomenon, it is best not to use. Try replacing. Find a good mobile charger, you can search to search for sale, quality assurance, safety and affordable. Frequency of use should not be too frequent charging treasure, charge and discharge too often, too often will shorten the life span, and will increase the chances of danger. Usually on the charger a good point, do not use it put pressure on crude way, usually careful not to stress, wrestling, in strong vibration, in order to avoid short circuit, short circuit to let her burn hazard occurs when the charge detonated. Choose presence batteries batteries quality defects, other accessories designed to re-well, this mobile power quality can not be guaranteed. So mobile power batteries are the most important part, is the first choice. Currently mobile power batteries, there are two, one is 18650 lithium-ion batteries, lithium polymer batteries one is. What is 18650 lithium-ion batteries? 18650 originally refers to the battery charge form factor Shenzhen Bao, diameter 18mm, height 650mm. Now more than that kind of like the 5th battery lithium-ion batteries. Such high dielectric core storage efficiency, the theoretical storage times for 1000, does not contain toxic substances, absolutely safe and environmentally friendly. 18650 lithium batteries due to the use of liquid electrolyte charging treasure USB charging, when the occurrence of overcharge (overcharging), the internal pressure will surge. In order to avoid an explosion, usually 18650 will be equipped with a safety valve at the top, when the batteries internal pressure, the safety valve will automatically pop up at the top, in order to play the role of decompression. But even if the safety valve pops up, batteries will not explode phenomenon, but the batteries leaked internal lithium ion and oxygen gas as a result of contact, there will still be a fire phenomenon. In order to reduce the risk of fire, 18650 lithium batteries should be in supporting a protection IC to prevent overcharging (over discharge). Charging treasure that good, large energy (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 welcomes all inquiries negotiations to create a better future can master.
