I had ordered packets at Amazon 3 Accu, The accus officially a low self-discharge, but with me it came completely unloaded at, Then the accus were a few more times recharge. After 1 week, the first package was broken, returning went. Now after 10 weeks, the second package is broken and Amazon refused to return (only possible within the first seven weeks despite two years of EU guarantee), so I have as a customer after 10 weeks already 66.6% defective goods. For the accus are abundant expensive and environmentally friendly is not. The one star I give just because less will not do.
