Since LiIon batteries can burn explosively I wanted to buy an original battery for Samsung Note. I thought in the price range> 30 Euro should not be a problem. However, I was surprised when I (etc. Seal, hologram) was the battery of 1A Electronics-house (Amazon Marketplace), as opposed to previously obtained Samsung spare parts in a neutral bag without security features. The dealer told me that this is Samsung bulk for mail order - however, pointed in the article description does not indicate. With regard to size, labeling, weight, charging and discharging so far I could not detect any significant deviations from the battery supplied with the phone. Due to the increasingly bold forgeries (even with drugs) remains an uneasy feeling if I have here really get original commodity. It is unfortunate that Samsung LiIon batteries not equip despite their considerable potential hazard with security features.
