2 times bought

this battery I once bought 2, namely for the first and for the last time. While he fits of its dimensions wonderfully into the battery compartment, but electrically it is for a short time only special.
This battery I bought due to the low price and because of the high price of the original batteries months ago about 7.
He initially worked quite well; but was striking from the outset that the performance lasted much shorter than the original battery and the performance is always terminated rather abruptly; was therefore of the first signs of total power failure then getting a very quick way.
Now after a good 6 or 7 charge cycles it can be not at all invite more; I had him first overnight in the charger and then even for 24 hrs .; Result: he takes zero to power, is now a total failure and ripe for the hazardous waste.
And so is ultimately very quickly from supposedly low expensive; wiedermal saved at the wrong end.
Can all only advise against these batteries.
