Man, I am a believer in that! This thread definitely validates that thinking as well. I purchased a Schumacher automated 3A maintainer for my Odyssey. I purchased another automated maintainer, and kept my lawn tractor's battery healthy for seven years. Considering that the tractor gets used for about half a year, then just sits for half a year, wash-repeat, year after year, that's an achievement for a teeny little low-tech FLA battery.... I now believe everyone should have one of those battery conditioner/chargers. The batteries of yesteryear never needed maintenance because they only needed to support the starter - not all this background computer and security system crap.
I'd use any of the high-quality brands mentioned in this thread. As well, I bought three more maintainers, and sometimes have all the cars hooked up on very cold winter nights. SW Oklahoma, most of Texas, New Mexico, Arizona, Nevada get brutally hot summers and then swing to snowy winters. Car batteries get a lifespan-depleting workout here.
