We may be old and have a few things to learn, but if you ever need some one to fix your unit when the parts are NLA don't ask us for help. Metz, when you grow up and start listening to those of us who have been around the block more than once, you can start making sarcastic remarks. We probably don't know everything, but I'll bet we knowva lot more than you give us credit for. A wise man once said, " before you say someone is wrong, make sure you are right". I'm sorry, I forgot we were talking about batteries. Who makes a sulfated battery? Interstate, Diehard, Everlast, or AutoZone?
