Looking for a little help. One of my Riva batteries is feeling a bit ill and decided to throw a temper tantrum. It's been a good little soldier for the last 6 months or so but today something out of the ordinary happened. I discovered the problem when the button was lit without been pushed, so I pressed it down and it went off but wouldn't come back on again when I then pushed again. So I just put it to the side and used a different battery. Well, I noticed it blinks every so often now. I'm afraid to put it on the charger in case it shorts it out and I end up losing more than one battery. I don't believe it's a charger issue because the rest of the batteries are fine. Has anyone else had this happen? Is it safe to charge it again?
