dang, I was going to suggest mine charger till I realized it IS the schumacher speed charger :P Oh well. You can get some pretty nifty battery tenders that will supply 2-5A depending on the battery's needs. Check on NAPA, I think it was like $65-70, designed to mount inside the engine bay with a short power lead, so you could hook it up to an extension cord. I have the simplier version, 2A trickle charge with a load sensing, so it doesn't overload the battery. It was only $30, but I'm not sure how effective it would be for an alternator-less daily.
