Hi, all. I joined the forum several months ago but I think this may be my first post. We've had our 16 ft 2001 Spirit Deluxe over 6 months and have had no trouble with the battery, an Everstart Maxx-29 Marine. When unused, it holds its charge at over 12 volts for months without charging. Today, when I was trying to disconnect the 4 or 5 wires from the bolt-type part of the dual + terminal so I could install a 7 wire junction box, I found that the nut was jammed on, either cross threaded or possibly with the wrong type threads. By the time I had the nut about 1/3 off, I realized that the bolt was turning as well and was unable to get the nut the rest of the way off. I tried prying it up with a screwdriver while unscrewing, but that didn't help much.
I would appreciate any suggestions about how to finish removing the nut (there's no room to grasp the part under the wire connectors). Also, even though the battery has a small round sticker with 3/11 on it, it is very clean and new looking. It's hard to believe it was bought back in 2011 (will look through papers from seller for possible receipt). Another question: Is the battery ruined because of the spinning bolt, assuming that it can be refitted with a new nut? Also assuming that it makes good electrical contact and doesn't leak acid. The rest of the dual terminal looks fine. If it is ruined, I might be able to saw off the nut without ruining the wire connectors. Thanks for reading!
PS: If I have to replace this battery, which doesn't seem to be available anymore, what would be a good substitute?
