If you only ever do very short trips in the car, keep an eye on your battery voltage…
Starting the car takes electrical energy out of the battery and a short drive may not put enough energy back into it to bring it back to where it was before the start. With lots of short trips, over time the battery can get depleted. A larger Ah battery capacity will allow a longer time between depletions as such. Longer drives will also allow the alternator to charge the battery more effectively.
Periodically putting the battery on a maintenance charger overnight will also do the same and places less stress on Tne vehicles alternator which isn’t really built to chanrge a dead battery…
So it’s not just CCA that matters as driving behaviour also plays a part…
