Have any of you used ONE Battery Tender Jr. over the winter to maintain TWO bike battery’s? If I connect 2 battery’s in parallel and hook the Battery Tender up to one of the battery’s am I asking for problems?

Damn, I typed the answer and had a glitch...here goes again.
I have used mine to charge a car battery that was larger than 2 bike batteries, so size will not be a problem. My only concern would be if 1 battery was bad and 1 good, would the brain of the Jr. freak out.

Battery Tender does make a multi bike charger

I just rotate mine between 2 or 3 batteries, every week or 2 as i think or it.
Two car batteries and the bike .

Now that’s a good idea. I’m just too dumb to think of something that simple I guess. I was more worried about messing up the battery’s than I was the charger. A messed up charger won’t leave me stranded in BFE.

Now u just have to remember to switch the charger every other week. Life is never ez....

Actually, I believe it does present issues with the full float circuitry where it may not shut down charging in one or the other battery resulting in an overcharging situation.

Why not just save your allowance money between now and winter and buy a second and/or a third one as needed?

I picked up one from WallyWorld a couple weeks ago for $15.00 with full float

Just Do It !

Allowance? The only allowance I get is a Blow Job every once in a while.

$15 for "Full Float"? Sounds like a good deal. Whatever the hell Full Float means. Sounds kinky. Thanks.

Buy another charger.
