You guessed it, the cold weather turns up and the battery turns up its toes. Where is the cheapest place to buy a replacement guys? Moto Rapido have one on the shelf at £90 squid. is that my best option?
Bike has a two year warranty...battery has a six month warranty!!! My generator went bad but I initially thought it was the battery. The guy at the dealer told me this because I was at 5 1/2 months when it happened. Guess it's possible he could have been blowing smoke. I never went and got a second opinion since it turned out to not be the battery.
My battery went all useless at the beginning of this year, just over a year into the warranty period. The dealer replaced it FOC. If your battery was fried because of a faulty generator, or if it went T/U for any other reason, it should be covered by the two year warranty. I say "Go for it".
General opinion in the UK seems to be that dealers will cover the battery under the 2 year warranty if they are being decent about it. I've had the offer, but didn't do it because I found the fault that I thought to be a weak battery to be things like loose earth connection or dodgy connection on the Optimate lead so it wasn't charging properly.
£90 is the price for a genuine replacement part from Ducati. Should be able to get one for about £55 ( GS ) at Italia Moto if it's not under warranty. It's GT12-B4. The originals can be very short lived, Ducati now send different batteries out with the bikes that come with a acid pack, rather than being "ready to use!!" As Henry say's check the main earth, it fastens on to the rear cylinder on the l/h side.Even if it seems tight loosen it and clean the contact area, if poss. give it a coat of vaseline or similar to stop corrosion, then retighten it.
