So the weather is getting colder here in Michigan and when I bought my bike last summer it came with a trickle charger. When if ever should I use this? When the weather gets cold I will be moving it from a heated garage that occasionally drops in temp (when both doors are open) to a heated basement where it will be 65 all winter. Should I keep it hooked up the whole time it is in the basement? How should I use this or is it worth it? I think the battery (which works fine now) is original and the bike is an 04 lightning. Thanks for the help for such a simple question. My 1st bike obviously.
