The starting battery ages when the vehicle is sitting, been drawn down much more than in normal starting use by the ECM, or by self-discharge if disconnected. In normal daily use, starting batteries seldom get pulled down below 80-90% of the full charge. So periodic condition checks are in order, if it sits a lot.
My experience with starting batteries is that the failure mode is often at least one cell shorting under starting loads.
