Times have also a battery of Duracell bought and even this was not worse than the original. Therefore, since you can already speak of rip off the original. Not with me. The original Canon can somewhere else!
Remarkably, the battery of Patone even 2 grams heavier than the original. There are also low-cost companies, which then significantly less than the original weigh and also by keeping much shorter. Patona belongs fortunately not one of them.
The company's address or registered office, I find somewhat dubious: Mallorca.
