Title: Warning, these leak
Review: I used RayOVac batteries for quite a while but lately I've had problems. For those batteries date-coded Dec 2017, they leak after just a month or so. In fact, in my back-up stash (just refreshed for the winter) batteries, new and still factory sealed, purchased at a reputable store less than one month ago, were leaking in the package. I can't talk about life-span... I went though all my equipment and all but one of these batteries were leaking. Got rid of them all. I hope they improve in the future and I'll try them again.
