After my old battery was after 2 years scrape ever just before, I have a spare battery ordered here. The first day he makes a good impression. However, I'm never sure whether it really is an original. On the battery supplied with the mobile phone is always namely: Cell Made in Japan, assembled in China. On this is just made in China. I noticed even at a few different batteries. In addition, no production date on the battery and he had numerous scratches.
