Mobile power battery Most of the batteries are lithium batteries. However, lithium batteries are also different, there are liquid lithium-ion battery and polymer lithium-ion battery two. The latter's safety, repeat the number of times, and so are better than the former. Lithium-polymer batteries are generally made of ultra-thin, the thickness and the phone almost no less. 1 cm about to put. Liquid lithium-ion battery, also known as 18650 battery, is the technology more mature batteries. Notebook, most mobile power, some electric cars are used in this battery. The capacity of a section is about 2000 to 2800 mAh. Samsung, LG 18650 batteries is better manufacturers.

Polymer battery: standard voltage 3.7 V, shape more, can be customized, with capacity, wide range of applications, such as: mobile phones, MP4,

Portable speakers and so on. Polymer battery mobile power some of the advantages of appearance by the shape of small batteries, most of them are very fashionable, can be more light thinner, more portable, and more secure. The price is relatively high, the pressure on the stock is relatively large.
18650 lithium: standard voltage 3.7V, small size, large capacity, the standard voltage of 3.7V, mainly used for notebook computers and other high-end products. 18650 lithium battery characteristics of mobile power by the appearance of the shape of the core, although the high cost, but the portability is relatively poor. 18650 lithium battery for the column, a single cell for the 2000-3400mAh of electricity.
AAA Ni-MH battery: standard voltage 1.2V. Capacity is relatively small. Widely used, household appliances, toys and so on.
Lithium iron phosphate battery: standard voltage
