I had done due deligence in reading the manual before I purchased it. It was a microprocessor controlled system that had a float mode. It was not cheap; cost was about $45.00. The charger/maintainer is a Schumacher. The manual said that "the charger is supposed to go between charge and Float-Mode montoring automatically" based on the charge in the battery in Maintain mode. I had it in Maintain mode function. My other Xfire is on the same type charger with the same setting and that one is OK.

It is a 2005 with a new MOPAR (6 months old) maintenance free battery. Oh well I'll report what Schumaker has to say in the AM. They are closed now for tech support.
