I had to replace the battery in my 2014!. The only one available at NTB (I has to get one quickly, and have it installed) was an Interstate MT-Line (MT 121R, 600 CCA, 5 yr warranty). When we got it home, and from reading some of the other threads in this forum, we noticed it is much smaller than the original one. Is this a problem? Does size matter ;-)? Should I return this battery and get another one? Any opinions appreciated! PS: we live in a relatively cold climate, outside Boston.
