Hi all, just back from vacation and worried about my battery, its the oem Panasonic in my 2012 TTSE. Sounded a little weak after the time off and so I charged it up but it still seems to turn the starter slower than I remember. It is 65k and 5 years old but I have had experience with Panasonic batteries lasting longer. Does anyone here recommend buying a new Panasonic from the dealer? What are your thoughts on the alternatives? Especially the Optima's and Odyssey's? They can be quite pricey but do they have the longevity? Any help would be appreciated since I am probably going to need a replacement soon; batteries rarely give notice that they are in decline they usually just crap out one day. Thanks everyone.
