Cell phone battery classification
We use our battery-powered products almost daily, and we'll be getting more exposure to it later, but do we really know the battery's quality and classification?
Currently cell phone batteries can be roughly divided into three categories, original battery, fake battery and domestic brand battery.
The original battery is the mobile phone brand certification or the specified battery, the performance and compatibility of these batteries is certified, the technology will also get the brand's support, is the consumer's first choice.
Fake batteries are mostly from the cottage factory, low cost, multi-use inferior batteries, standby time is very short, and unstable, the output current is not stable, prone to voltage drop after the battery is used for some time, no protection circuit, easy Damage, news reports common electrolyte leaks, explosions, etc., are caused by fake batteries.
The third is a domestic brand battery, or as a compatible battery, that is, a third-party manufacturers of batteries based on the standard of a certain brand of models.
People should pay attention to the purchase of cell phone battery, one cell phone battery nominal voltage and your cell phone voltage to be consistent. At the same time, can be switched on experiment. The second is to obtain the relevant technical quality supervision department of the battery sampling test of the document, the indicators include the battery capacity can be clear at a glance, from the battery capacity indicators. Third, pay attention to save the warranty card. Specific purchase from the following five aspects.
Fake and shoddy batteries exist in the general problem is: the battery core components of poor quality of battery chips, insufficient charge, discharge time is short, anti-sabotage performance is poor, the standard battery capacity and the actual discrepancies.
Genuine mobile phone batteries generally have the following appearance characteristics: Battery label using secondary printing technology, under a certain light, from the bevel, the bar code part of the color was significantly blacker than the other parts, and touch up by hand, feeling slightly more than other parts Convex, many original batteries have this feature. Genuine battery label surface with white metal scratch, there are traces of similar pencil across. Battery case made of special material, very strong, not easy to damage, under normal circumstances is not easy to open the battery case, the battery looks tidy, no extra burr, the outer surface has a certain degree of roughness and feel comfortable, the inner surface smooth, light Can see the fine vertical scratches.
The width of the battery electrode is the same as that of the cell phone battery. The corresponding position below the battery electrode is marked with "+" and "-" marks. The isolation material between the battery charging electrode pieces is the same as the material of the shell but not the same. Battery into the phone should feel comfortable and comfortable. Battery lock part of the appropriate pressure card, solid. Battery label clear writing, with the battery type corresponding to the battery part number. The battery manufacturer should outline a clear, and security signs bright, looks three-dimensional.
Weigh the weight
Under normal circumstances, the lithium-ion battery lighter weight, each battery is about 100 grams; taking into account the obvious characteristics, can not be arbitrary counterfeiting, we can use the method of measuring the weight of the phone battery to identify whether the battery belongs to " Selling dog "type, after all, other types of batteries, and lithium-ion batteries in the weight difference is relatively large, simply called a weight, if the battery is too much weight or too far from the 100 grams standard, it can be roughly inferred The battery is fake and shoddy products
Look at the phone's appearance
Here to see the appearance of the phone, in fact, refers to a careful observation of the appearance of the cell phone battery color, whether the appearance of the phone with the same color. Under normal circumstances, the appearance of genuine color cell phone battery with the appearance of color is exactly the same. Therefore, we can just picked the battery is installed on the phone to see if they are the same color, if the appearance of the color between them, there is a clear color difference, the battery is likely to be fake and shoddy products. The texture is different
There are some types of cell phone batteries, we can completely in accordance with the texture of hard or not, to identify the authenticity of the battery. Press the cell phone battery arched junction, and use your fingers to directly feel the point of the soft and hard degree. Usually, the texture of the genuine cell phone battery is softer, but it also shows a certain elasticity. Especially when the battery is inserted into the cell phone, there is a smooth and non-blocking feeling of inserting freely, With a very harmonious, stable lock; the other hand, poor quality of the battery is relatively hard on some, and the battery is installed, it is not easy to "slide" into the cell phone battery slot.

Look at the charging effect
In general, the superior performance of mobile phone battery, the internal over-current protection device, once the external short circuit occurs in the cell phone, triggering a large impact current, the over-current protection device can automatically cut off the charging circuit to avoid cell phone battery due to high current Impact and damage or burned phenomenon. Poor batteries, there may not be over-current protection device; so long after charging the battery, there may be hot-rolled battery case phenomenon, serious smoke may occur. If the battery does not take long to charge, there is a phenomenon of hot, then the battery is inevitable ten thousand.
No matter what we buy to learn to distinguish between the authenticity of good or bad, buy the battery even more so, because it determines the life of all your electronic products, so learn to distinguish, choose the right battery store, buy the right battery is your The greatest help for cell phones.
