+1 on the Optimate. Had a Battery Tender Jr for a while but got an Optimate for Xmas and it's great. I've got a Mighty Max lead acid battery in my 2015 DCT at this point.
I have an Optimate also. The YTZ14S battery in my X-Adv requires it on a regular basis because of the current draw of the tracker that the Insurance company forced upon me. One of its benefits is that (once one figures out the lighting sequence) it indicates the overall condition of the battery. It notified me recently that while my Strom battery was functioning fine, it was definitely declining. The voltmeter also confirmed that.
