I would like to vhbw still following note: I had just ordered the wrong battery, and turned me for a return immediately vhbw. The next day I received a Retoureschein email, and 2 days later, Amazon has informed me that the purchase price had to be referred back to my checking account. In addition, even for the wrong delivery vhbw apologized, although it was clearly my mistake.
For this great service I would like to thank vhbw and Amazon again!
