Thanks for your reply. Can you clarify - what does the stored reading of battery capacity at 80% mean exactly?

Smaller batteries simply have less reserve capacity at a cost of shaving weight - drive often.

Maybe you haven't read the whole thread. Do you have comfort access, Bluetooth? It was suggested (perhaps speculated) prior in this thread the comfort access may create a higher drain on the batter during the time the car is not used. My 21 lb B3121 simply can not handle two days in a row without driving, let alone simply being started once a week. Sure the car will start but the clock and trip odometer get reset and CA starts to not allow the one touch open. Something must be different, either our cars or our batteries.
