a well maintained wet cell battery will last 2~5 years. further, ducatis are kind of mean to batteries, so they fall out of good health unusually quickly. the ducati regulators are not good at charging batteries, so it's best that battery tenders or other chargers "charge up" batteries, rather than rely upon the bike's charging system.
once the charge warning light comes on, i feel the RR is on it's decline, though it may last a couple more years with the light occasionally flickering.
I'm still sticking to my "I'm not an idiot, though my idiot light is on" theory.
Went out at lunch and the bike won't start. :
So, to paraphrase, Chris, I need a new battery and to perhaps hard-wire a battery tender connection as well. Is this the correct assessment. And I don't need to spring for a new regulator? Thanks, man.
you can try life without the new regulator, but i still think it's on the downward spiral. regardless of the regulator's health, you're going to need new battery + tender anyhow. AND if you DO need a new RR, best to have the fresh battery before hand.
when you get the new battery (And tender) be sure to charge it nice and slow for a couple days. you need a good initial charge. this seems to make huge difference. more so with the sealed batteries on newer bikes.
