I only have a tender that won't revive a dead bettery (safety feature, I guess).

I can boost the bike with a car (vehicle off, ignition on), but since the ground is covered in snow I wouldn't be able to ride it. Can I boost it that way off a car, let it idle for a bit, bring it in and put it on the tender?

I only need enough power to let the tender bring it back up.

 

Take the battery off the bike, let it warm up indoors and your tender may do what is needed.

 

Tender won't have anything to do with it, unfortunately.

 

Borrow a battery charger, use the 2A setting. I'm not sure I'd try to jump a motorcycle battery with a car's charging system. Too many amps could blow it up.

The Deltran "Battery Tender" needs 4.5 volts to trigger the charger, you can put it on a generic charger to get it up to there, then use the Tender to get it healthy.

You'd have to get your bike up to at least 1200 RPM to charge, idle wont' do it.

 

Hm...well, I'll try to see if someone has a battery charger I can borrow. If not, I'll jump it when it gets warmer out.

 

You could always take it out and take it to Advance Auto to charge for free.

 

as long as its not frozen you can jump the battery with a car, or just take it out of the bike and put jumper cables on it and hook it to the car battery for some few minutes, just to get the voltage up enough for charger to take over....you can jump it right on the bike if you want, but its hard to get the cables on without shorting something with the cables.....its just like jumping a car....

 

I was wondering if that were possible.

 

A battery that is that low and has probably been frozen, might not come back.
