Check your Halo batteries

I just got my Halo lanterns. The first one I pulled out didn’t work. When I looked at the batteries I saw that one of the batteries had started to leak. Checked the other 5 lanterns and they are all ok. I expect to need new batteries, so that was no big deal, but I don’t recommend leaving a leaking battery in place.
