How to choose the right consumer Button batteries Button batteries would have to grasp the common sense and methods.
As technology advances and demand expansion, electronic tags are increasingly so well known. Depending on the volume of applications is getting smaller and smaller, so that the more applications also will choose the smaller battery. So now more and more electronic tag use Button batteries, often used in the Button batteries of 3V Lithium Button batteries and 1.5V alkaline manganese Button batteries. Currently in the domestic production of such Button batteries manufacturers are also numerous. I do not quite understand the electronic tag in which to share with everyone the knowledge of the battery label.
3V and 1.5V Lithium Button batteries Button batteries are alkaline manganese dioxide as cathode, lithium foil as the anode, electrolyte combined to achieve the discharge effect. Currently all manufacturers, because differences in the production process, as well as optional battery materials are different, so the price is different, in general, domestic battery battery to a lot less than in Japan, but now the gap is getting smaller and smaller, made to do good The battery and battery performance in Japan is very close.
Why domestic battery with Japanese battery and domestic battery performance will be greatly between the gap? First, production processes, quality control is critical reason a second, causes cell materials is quite large. Process issues that each company's core secrets, but also each company based on the book, which is, we could not be traced, but the problem of raw materials, we can analyze, can be judged. Button batteries the core material, which is the raw material will affect the battery performance (which were excluded from the positive and negative material is not sufficient in the case, now many manufacturers from the profit point of view, positive and negative terminals of the battery materials cut corners, resulting in battery really hateful cause and which is not within the scope of our description) main gasket, manganese powder, diaphragms and battery cover. Sealing gasket, whether directly affect battery leakage, and battery storage performance, almost the sealing gasket is easy to aging, but aging one, then leakage, leakage problem will then arises. The purity manganese battery performance is great, impure manganese powder can cause uneven discharge, inadequate capacity and other phenomena, which need to see whether there is such a battery manufacturer specialized departments of detection. The diaphragm is stationary discharge a very important raw material, the density of the separator is too thin, the discharge will be too fast. Too close, you may put no electricity. Battery shell is a battery electric conductivity is good a guarantee. Currently on the market used battery shell of stainless steel and iron, of which different materials on the battery is also very different.
Insiders reminder: buy Button batteries when the battery carefully View appearance, type and size. The packaging rough, wrong type of printing to be careful not clear product purchase. Never buy no name, no address, no current, no voltage and battery level indicator and battery warnings batteries. Found a serious shortage of battery capacity, voltage instability please do not buy. In normal use the battery if there is overheating, battery shape bulging rupture phenomena, should immediately stop using it.
