18650 capacity, generally the most common are 2200mAh, 2400mAh and 2600mAh three sizes, according to the current 18650 has introduced the largest single section can be done 3400mAh capacity. 18650 using mobile power, is more than a few basic specifications parallel implementation. 18650 generally use cylindrical steel packaging, the internal lithium ion in the liquid state. As it has been the industry standard compliance specifications, 18650 cylindrical mobile power only if everyone in the purchase of mobile power saw thick and big shapes mobile power molipow, is essential to determine the use of 18650. Polymer batteries polymer batteries are divided into three qualities, namely product A, B goods, C product A product polymer batteries is the best quality new polymer battery, battery manufacturers are usually custom-made on quality requirements are relatively high, all parameters can compliance, without any unusual products. Under normal circumstances the big manufacturers of mobile power will use A product batteries. B product polymer batteries such batteries mobile power magic bubble in the production process, for some reason some products can cause flaws in appearance, capacity, voltage, or other parameters have a little problem, so the product is called B product . Also, if A product batteries stock for too long, such as 3-6 months without shipping the product, usually also called B goods. B products 1-2 months of use of the previous product with almost no difference A mobile power investment, capacity, and a sharp decline in the number of cycles will be two months later. C product polymer batteries like 18650 disassemble products, usually discarded batteries, poor quality, usually in appearance, capacity, voltage and other indicators are substandard. Such products there are security risks, has the power to move its production capacity not only on the problems, is likely to cause damage to the digital devices. Consumers also need to be wary of buying. Mobile power quality, large energy (certified), mobile power provided by the Shenzhen Municipal 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.
