Bests & Worsts Reviews from Amazon

I thought these would be a great deal since I have quite a few pedals and active basses that need 9v batteries. Also seeing the amount of star ratings thought I couldn't go wrong. But these things can't seem to keep a charge even when I unplug everything. I've also had the same problem as a bass player who reviewed these batteries. The battery is too tall and fat for tight battery cavities and don't last long enough. You can see from my attached ***PHOTOS*** that it doesn't even fit in my battery compartment w/o smashing it in and you don't want to do that because it'll bite into the attached wiring. There are more cons for this particular usage than there are positives. They may work great in other applications but I'm going back to buying regular brand batteries for my electronic instrument needs.
