Pay attention to the packaging. Crumpled packaging is downright screaming: there is a fake battery. She may give a fake head. Typographic print of the original is much clearer, sealing packaging looks like a stick with a circle, exactly glued to the hologram.
Be sure to check the documentation. The presence of the user, the compatibility list disposal instructions required. Documents should be in multiple languages. But the characters should alert you. The Chinese market is a separate segment for manufacturers and nothing to do with us not have.
Pay attention to your original battery, and is generally better to buy new to take it with you. Carefully compare the appearance of the devices. Despite the fact that often they look very similar, there are things that you guard. Case material – it is slightly oily to the touch input. The contacts of these batteries plated alloy with smooth uniform Golden color, no scratches or potreste.
Look at the label of the battery. The original must be the icon in the trash not thrown away, print labels more clear, the sticker on straight, the letters are in any case not circumcised. Shake the battery, the original should not do inside to hang out. Fake can and weight to be easier. Original battery should fit snugly and not hang out in his "house".
From a fake you can keep buying "live" in a specialty store, from an authorized dealer.
