Yes. In 1965, the battery's job was to deliver 350 amps of current for a SHORT time to get the car started -it's job was then done and the alternator restored the battery's charge.

Today, it is an entire new world. Today, the battery has a second job, that of capacitive filter. That is, it is called upon to act as a huge capacitor, providing CLEAN power to all the modules and systems in the car.
The DC electrical supply in a car is a hostile environment in which to put sensitive electronics that are based on LSI and VLSI (large scale and very large scale integrated electronics).

As the battery ages, its ability to deliver enough current to start the car degrades. But what degrades faster, is the battery's ability to filter.
