profiteers who are debited by unauthorized phone accessories sold separately to earn them a profit.

For example: a European version of the Nokia E72 itself should the data cable, charger, original battery, memory card, headset these parts, the price of this machine is 2000 yuan (Note: The price is only a hypothesis), and dealers by deduct the original battery, replace it with a high defense or leave the battery on the price of 2,000 yuan to sell you, then the price of 200 yuan a separate battery out to other users, so that a European version of the price of E72 2,200 yuan, so a machine will earn at least 200 yuan of profits, showing how deep inside the "rules."ASUS N53 battery

Of course, in the absence of exceptional circumstances, we can only use measurement tools to identify genuine and fake batteries naked eye.

1. Laser trademark, trademark laser really watch battery back above three-dimensional images appear in a different location, but the vast majority of fake or imitation batteries can not do that.ThinkPad X61 battery

2. The materials across the cell should really hard texture of the material silica gel, and a small hole in both ends of the battery of electric shock should have perfusion of special materials or liquids, usually after fake dug into, there are significant differences.Aspire One ZG5 Battery

3. Leave the battery contacts arranged in irregular shape, the material under shock mostly white plastic. Really neat battery contacts distribution, no protrusions or recesses phenomenon.
