I've been using these batteries for the past 5 years with no issues at all in my games. The only issue I did come across was that a couple of batteries had the polarity reversed on them which killed the batteries that were paired with them in the game. I couldn't for the life of me figure out why the game wasn't holding scores so I tested them with the DMM. If you have a local Sam's Club then you can get them there for a decent price.
