The old torch shines again

We have an old pretty strong flashlight that we do not use so often. The Duracell Ultra Power batteries they immediately began super bright glow, which indeed is normal with new batteries, but I have a feeling this Duracell give initially very much power as to whether it will also last as long as the cheaper batteries I can Now of course not judge. The Power Check is a nice gimmick, actually you do not need something like that, you realize all so when the batteries become weaker.

Conclusion: The flashlight works and lights up very well, because it is rarely used, the batteries will probably last a while. If not, I will add a response.
