We had single digit temps at night, mid 20's in the day (up to 37 today).
I let the Rocket sit 4 days without starting, fired right up when I got home from work yesterday.
Still too much snow and slop on the roads to ride.
I got my Odyssey charger yesterday. I'll hook the pigtail up this weekend.
With a proper charge, this battery goes the distance.
The Battery Tender didn't give it the juice it needed, but apparently the jump from the car battery did.
This post has it right.
