Bought this one to replace the same battery I had bought just less than a year ago that just up and completely died with no warning and of course it was out of warranty, hope it was just a bad one. Other wise up until it failed I had long run time and good cleaning this is why I said but in the headline. The battery appears to be of quality on the outside but the internals could be questionable, I just don't know. Hope this one last longer than the first. If battery life is no better than this it should be removed from site that's a fair chunk of change to spend in such a short period of time for something that should last for years.
