converter problems

[ianoc2]

Have a parallax 7300 7 years old now. I have never been able to leave a battery hooked up as it burns them up in about 1-2 mo. Now the fan is out and the 12vdc is fluctuating badly. I want to get a new convertor but most mfg. do not tell you which ones are ok to leave a battery hooked to. Not interested in a generator. 7 years is not too bad but sure would like to keep the batt hooked up.
any suggestions as to mfg. and model would be appreciated

Most Keystone trailers since before '06 have used three stage converters. You may get better advice from a forum for Forest River. If working properly a three stage converter will not boil out your battery. This is the type you should look for replacement. Hope this helps, Hank

mine is a wfco 3 stage. it is a fairly cheap converter. I am on my second one and this one appears to be much better than the first one. and I don't have a problem with battery boiling
