Battery charging and maintaining ?

Unless things have changed, Winnebago began installing the Trik-L-Start on coaches with the 2007 models to insure both sets of batteries charged while plugged into shore power. Check your coach and your literature, you may be wasteing a worry.

I did the mineral oil trick on my lead acid house batteries and eliminated the problem of cooking the batteries and related corrosion. By the way, I also replaced my OE Parallax 7455T Charger/Converter with a PD 9260 unit which uses three automated charge rates.
