Property me this battery ordered as a spare battery for my Olympus E-520, after one of them was me just too little, because I always had to stop taking pictures when the battery was empty. So I was looking for an inexpensive, yet powerful alternative to the outrageously expensive original battery from Olympus. First I looked at the very cheap variants, which, however, according to reviews, to ever suck anything. And problems with the camera due to a faulty battery, I definitely wanted to avoid.
Then I came across this spare battery, which immediately convinced me because of the reviews and the brand name, because I've made very positive experiences with Hama. And so it is with this battery, in which I could see the slightest difference with the original battery so far neither in power nor time.
