Do a search here on battery tender and you will find all of the info that you are looking for.
Ya, but Chaparral has got the standard ("Plus", not the "Jr.") on sale for $35 (list is $60).... the Battery Tender Twin is $170.battery tender makes one that does two at a time.
I believe that is the one I have-at least that is the brand.it is a SCHUMACHER Fully Automatic Battery Charger for $24 – does anyone have this one – are you happy with it – any other recommendations?
