My copy: inferior, short-lived waste

Wrongly received in January 2014 such a battery instead of a 1000 mAh battery of the same label and dispensed simplicity on Exchange. The battery never reached the capacity of the original Panasonic batteries (in which only 695 mAh are given) and also not my second battery (noname) - both were there been 5 years in use and have been valued each loaded 100 times. After about 6-9 months was revealed then finally the "Guaranteed Premium quality of the German battery label: MTec": the battery swelled and then tucked inside the battery compartment, could be seen only with gentle force. Needless to say, that he was there also no longer prepared at all to supply power. There were estimated up to 15 charging cycles (original charger) achieved rather less.

As a look at the reviews of 1000 batteries MTec shows, I would have gone any better with an exchange. Also there stands the "Guaranteed Premium Quality" by questionable performance.

Please avoid this brand better.
