Call me crazy but I don't like leaving any charger/tender pluged in while I'm not around. Cordless drill, flashlights, batteries, etc...
I'm in my shop/shed almost every day, when I turn the lights on I power up my chargers too. I just don't feel comfortable leaving 110v plugged into a charger leading to a battery. Anything could happen between these 3 points of contact, although the stats are in your favor I just choose not to chance it.
Maybe its not the best solution for my tender and battery but I have had bikes all my life and I rarely have to buy a battery. Sure, maybe I have to buy a battery or tender a couple years sooner but the cost is worth my piece of mind.
Ride Safe or in this case Charge Safe
I'll give you another good tip. you know those plugs that cover wall outlets so kids won't stick things in and get shocked? Buy some and before you leave the house, unplug everything and cover the outlet's with these cover's. It'll keep your electricity from leaking out. Save on your electric bill!
Leaving it on all winter doesn't make sense. You'll just end up frying the tender. Just take out the battery and leave it in a closet where it stays warm. There is absolutely no point in leaving it on a tender all winter if you don't plan on riding the bike.
That is the point of using the battery tender. Plug it in and forget about it.

Been using the same one for almost 8yrs. Leave it on all winter.
