expensive batteries with adequate power TOP

I have the batteries now for 5 weeks, and a few unused batteries which I have charged the first thing (and then never used) since 12h hold the flashlight lights on now.
A record held an evening of lightning through well.

For long-term use of course I can not say anything. That reminds me, however, in the three months letztzen Ansmann AA batteries failed, I hope to come here to better quality. Expensive enough they were indeed.

After 8 weeks measured it all batteries and yet full. So I can not notice any problems as other buyers.

Update:. After half a year with a total of 8 batteries no failures, full performance of all batteries in many concert photos.
I would now only buy these Varta batteries.
