[QUOTE="RossKean, post: 1436058, member: 19880"] My bike sits in the unheated garage from early December until mid-to-late March. I don't own a tender so the battery gets a few hours on a 1.5 amp (max) "trickle charger" a couple of times over the winter. Nothing but a transformer and simple diode rectifier that is neither constant voltage nor constant current. I have a "smart" charger for car batteries and it could probably be used on its lowest current setting (2 amperes) if needed but it isn't designed as a tender - clamps are too big to fit easily anyway without physically removing the battery. The dumb trickle charger works fine when I need it and I have had no issues with battery longevity. (2011 bike still has OEM Yuasa battery although reserve capacity is dwindling as it ages - one more year maybe.) Got similar service life from the OEM battery in my 2007. [/QUOTE]
