This "Premium" battery, which promises initially a very good performance, disappointed but then in the long run.
The battery was initially recommended as fully up a few times and always timely discharged or re-complete charge but not overcharge.
If not excessive, but rather occasional use in exchange for the original battery by Canon of WEISS battery came more than 2 years, regularly used. In order for this direct Vergelcih me is possible: While both batteries provided at the beginning (about the first half to three quarters of a year) very good performance and a difference was so factually not determine this power was then gradually by the white. After over a year of white-battery no longer held by far the original with. At first, a crass short performance in the Cam was noticeable - the result: steady care, always carry two completely fully charged batteries. A few weeks / months later showed this then also to a striking short charging time in the original Canon charger.
Nor know my claims suffice just so, so I can not be a comparison with a third battery still (!). I would like to add, however, that I decided to purchase the white only after extensive compared to other batteries. And precisely because of there acclaimed longevity of Weiss batteries.
In relation to other battery seems (!) Of the WHITE therefore still to bring acceptable performance, so it is still reviewing the results with 3 stars.
