I just went on the first Spring ride since November to the dealer to have the Key Fob recall taken care of. I was thinking as my bike will be 3 years old in July (purchased in September 16 assembled in July) whether to proactively change the battery so I don't get stuck - I have 7k miles on the bike and keep it on a Battery Tender all year including in the summer when I ride it every few days. I noticed there is the Shorai that is put forth here and several other options on Revzilla including Yuasa and Anti Gravity as well as several power levels for each brand.

The battery sucked on my 2009 MTS, and I always carried a charger kit.

I would appreciate any experiences or recommendations. Also - Do bad things happen like on my Benz's if you change the battery without having it powered (electronic resets, errors etc.)?

It was interesting that the service manager recommended against a battery tender.

I rode the new GS 1250 while waiting and while it is a sweet bike - I still prefer the MTS 1200. While it is getting closer it still does not provide the same thrill factor.

I wonder why? My dealer not only recommends a tender, they install a CTEK charging pigtail on the bikes they sell and keep those chargers in stock.

I believe modern Duc's have a constant current draw with their electronics and eventually the battery will be drawn down to a potentially damaging level. That is particularly important for those that keep their bike in freezing weather. Maintaining the charge state is imperative for some level of freezing protection.

A few thoughts-

Did the service manager recommend against a Battery Tender 'battery' or the BT charger?

We have a direct fit battery for the Multi that has a full battery management system. This basically means that it is all but impossible to drain, since the BMS cuts off power when it gets below a safe level.
Our stuff also has what amounts to a built in jump start, so youll be able to jetison your charger. For the 1200, the 360 cranking amp version is the way to go: https://www.fullspectrumpower.com/collections/batteries/products/pulse-ipt-battery-p-12l

Ive written extensively about lithium here on MS, and in more detail on our website- so if you are interested in what goes into our products, here is a good place to start: https://www.fullspectrumpower.com/blogs/full-spectrum-news/full-spectrum-power-pulse-ipt-lithium-motorcycle-battery-technology

I wondered about that as well. Im guessing that the SM actually meant the Battery Tender brand, and not a 'tender' type charger, like the CTEK- which is a really nice charger. we use a CTEK on our shop truck and van.

All modern Ducati's do have varying amounts of parasitic draw, which can definitely damage a battery- unless you get a lithium battery with a battery management system (BMS) that prevents that from happening.

The Multi is a good candidate for that, as it uses a really nice Shindengen MOSFET regulator.

Don’t buy shorai. They have a bunch of fire lawsuits against them. Cheap lithium batteries are never a good option.

Battery Tender

The service manager recommended against a Battery Tender trickle charger and stated that his observation was that the batteries lasted longest when not on a trickle charger.

All I'll say is that a quality tender for winter storage is a must, especially in an un-heated garage. Notwithstanding, Ducatis have parasitic draw. A quality tender that manages both current and capacity will keep it topped-up.
