Has anyone used vmax Batterys? I bought 2 6 volt Batterys for my camper. I let them run all the way down. Did not mean to do that.I called them and actually talked to a person. He made some suggestions and I was able to get them back up to full charge.They even called me to make sure I was good. They make all kinds of batterys. They got a fantastic no questions asked warranty. If you buy from there web sight you can build points for your next purchase . Just my 2 cents.I have had problems with new glass mat batterys going dead all the way and I can't get them back up.
