I have my 999 on all the time, it's just a cheap halfords trickle charge, nothing fancy. The original battery lasted 11 years, I'm yet to fit one to my multistrada. I do ride pretty much all year round, that helps.
Good point. If you hard-wire an in-line connector for the charger, it is easy enough to unplug, kick over the engine for a few revs and then reconnect. I use a C-Tek and both my bikes have a socket fitted - discrete but useful.
My bike is being kept outside for the first time. its nearly 5 year old multi on original battery. never charged it just ridden it But this year I won't be riding as dont commute anymore .should I take battery out bring it indoors will that mess up skyhook suspension?
as far as I am aware, if you disconnect the battery of a fuel injection (ie post-carbs, say 2002 or newer) Ducati, the ECU will lose its settings and have to be reprogrammed. That's just a rumour I heard, but perhaps worth checking.
Here's a few pointers from a guy that went skiing yesterday. Winterization (Keep it simple) 1) Fuel stabilizer and run it through 2) Keep both tires off the ground 3)) Vapor barrier under it (rubber mat, plywood, plastic etc). This will prevent corrosion. Cover with a breathable dust cover. 4) Plug it in with a quality battery tender/charger. You don't need to remove the battery. Batteries don't freeze. If they did, roads in Canada would be devoid of cars during the winter. Most important. If you're an occasional track enthusiast, do remember to replace your Water Wetter with proper anti-freeze coolant fluid. Don't start it periodically if you're in freezing temperatures. This will do more harm than good. P.S. For those of you that live where you seldom have freezing temperatures: Why are you reading this? Get out there and ride!
