batteries overcharged.

Hi all, just wondered if anyone had any suggestions. We have a 2013 sp-240 which er took delivery of in July 2012. First trip out battery died the first night. Took back to camping world and the installed dual 12v batterys at no charge. Problem seemed to go away. A few months later we went on another trip( I had a couple dry camping trips in between this one) and had shore power. I plugged in for about 12 hours when I noticed that the fan on the power converter was still running. I checked batteries and sure enough they were sizzling. I disconnected batteries and let em cool off for a few hours. The weekend after towing it back to storage I rechecked batteries and both were fried. The sides were bulging out. .. I guess my question is this....is the power convertor supposed to charge the batteries or should I buy a charger and disconnect them whenever I'm plugged in? Also what is the brand name of the convertor? Can't find it in the pile of manuals I received.

Probably a fried WFCO converter that no longer modulates the float voltage or doesn't go into float at all.

Find it, (should be behind power distribution box) note the model.

You should be under warrantee still so take it back and have it replaced and a new battery. It is not that uncommon for them to go bad. They are cheap Chinese throwaways.

Also, a good reason to not have the camper hooked up without monitoring it, better to charge it up and disconnect when not actually using it.

Replaced converter. Problem solved. I don't leave it plugged in when in storage. I physically disconnect the batteries and leave a small solar trickle on the batteries to maintain.
