So this is the 2nd time it's happened recently...I went to go ride, and it wouldn't start...rrrr rrrr rrr click click click noises.I trickle charged it, and it indicated fully charged in only 2-3 hours which is faster than usual on a completely dead battery.

I rode for a few days no problem, then today same issue. It's hooked up to the trickle again.

I'm selling the bike ASAP, should I replace the battery? Is that easy to do on the savage?

Is there a standard battery for the Savage that's acknowledged around here as the tried and true?

I called my shop and they don't have one in stock for my bike so I can't get this fixed ASAP, but want to show the bike tomorrow. I'm gonna trickle charge it again but I don't want it dying 2 days after I sell the bike and having the guy be pissed.

I'd charge it to get the bike started to show it. Then I would tell the prospective buyer the battery just went bad, and knock off a suitable amount of money from the price. He'll undoubtedly want to dicker over the price anyway, and that will give him an opening discount. As a buyer, I would be happier knowing there was a new battery in the bike, but I wouldn't pay any more for it. Whenever I buy a used vehicle I always figure it will need some work, on the theory that the seller isn't selling it because it ran too well.

Just for giggles, what did they hit you for on the battery/installation.

Yep, A $20.00 install is pretty allright.
