Very durable and good battery

We already use the Duracell Ultra Power D batteries for a few years in flashlights / headlamps hand. Therefore, we now also write like a test under the vine-test program from Amazon. The Ultra Power D are produced by the way in the United States. In detail:

Positives:
+ The long duration of the batteries, much longer than no-name products, but also considerably longer than the other Duracell batteries (according to manufacturer's specifications 40%) (we, however, remove the batteries from the flashlight when it is no longer needed)
+ Stripwell I find very comfortable and the biggest advantage over its competitors in all the batteries in the pack have shown out of the box 100% (is new by the way do not, I know such a thing in years)
+ The batteries are its 10-year shelf life, which would be sensational (I could only check!)

To bear in mind:
- It is only after the purchase price, the result for the consumer hardly a financial advantage because the batteries are not only 40% more durable, but also are more expensive. After all, one does not need so much change and protects the environment
- An indication of the capacity in mAh would not be bad, but I can still do not apply to the battery on the packaging, indicates the indication MX1300 1300 mAh go?

Overall, still very good, but not quite cheap branded product. Thoroughly recommended.
