I don't know much about batteries accept I don't like them, lol, no seriously they are good when they work but a pain when there is an issue. Trying to avoid an issue I decided to add Inox battery conditioner to my group 29 everstart. I followed the instructions and then proceeded to charge it up. Thankfully it wasn't in the boat as it started to drip fluid out of the top after about 20 minutes, but didn't get very hot. I followed the instructions, any ideas? I'm afraid to even put the battery back on the charger, let alone my boat. I contacted Inox, but who knows when I'll get a reply.
