So my 1960's vintage Schumacher battery charger doesn't seem to be 100% these days. Plus I now have AGM Batteries in 2 out of our 4 cars. Cadillac has an Optima Yellow Top, and the Miata has an OEM style AGM.
So what is the modern way to go? I've seen mentions of Noco and CTEK as some of the better new age chargers. Also I see Schumacher makes a neat looking modern chemistry compatable battery charger.
Anyone got any first hand experience with "modern" chargers?
