I've got a solo battery that automatically turns itself on. I can turn it off, and a few seconds later, it comes back on. The button is not sticking. And strange thing, if I connect it to the battery checker I bought from a guy here on this forum, it will read all the data, says it has 1 cycle, and when I turn it off, checker screen goes off, and the battery stays off. But if I unplug the checker, it will come back on. Weird, or what? maybe it's possessed?
