Have an "ancient" - mobile phone, Nokia 6233, for about 6 years in use (and going and going ...). Work, even though I take it to work and not very tender so Bypass (often fell off, etc.), still top. The only thing is, I have to buy a new battery about every year and a half, since the power then slowly but clearly subsides. Have now bought later the now third, so the original time (Made in Hungary) to Handykauf supplied battery, now the Fourth (about 2 weeks ago). Had the reviewed here Battery bought and had him since he arrived already loaded, then after 6 days the first time charging, then a second time after 7 days (is still full display). Since me here some reviews concerning the quality "Made in China" battery pack unsettled, I looked one more time my "old" batteries to. As I said, the first was a "Ungare" the three successor "Chinese", but no matter. Do not remember that one of the previous battery was particularly good or bad. Also this one with its loading capacity of less than a week, to enable accurate power readings which had all my batteries, as they were still new (incl. The First, sozu. Original battery). In my opinion, "Made in China" does not always automatically, everything is crap. The least have my EZIG. invented and built, with the help of more than 35 years after I finally got away from the harmful nicotine and tar (where all other means have failed miserably very ;-). The Chinese people are quite capable of (making it just does not always) produce high-tech products. This includes, in my opinion, the battery-reviewed here, or I had maybe only when manufacturing tolerance simply luck (may or may not be, - personally I think it is not really). Anyway, for me there is nothing wrong in any case, "Made in China" or not.
PS. By the way, the old battery, bought here almost 2 years ago and "Made in China", holds at least another 3-4 days (rather than 6-7 days new), so would "Emergency default" to use his still.
PPS. Wondering just that the vast majority of 1 star reviewers on this article, have been written just exactly one review (currently 16) and the other, with one exception, at the most 6 stands for most the sentence "Amazon Verified Purchase" not there. Very strange. Maybe the battery is anyway better than imagined, when he may have been "artificially" made here bad.
