I've been considering a trickle charger myself, as my car sits over two months sometimes between drives and then gets driven a lot for a week or two (it lives at my vacation house so there are many reasons for this.) Point being here, that my S starts right up every time no problem, and is stored over 15C and on average over 20C with no charging in the storage period. I don't know the age of the battery, but it clearly holds a charge very well.
The solar trickle charger is your friend as others have commented.
