Back when I did my own maintenance, I'd change the battery proactively after six years or so.  They didn't cost much then.  I kept my cars a long time, not so much of late though.

HA! great minds and all that. Crap the new vehicles you need blueprints to find the damn thing

Wondering why new car batteries cost so much? Here’s the reason and how to save (news4jax.com)

You probably grew up with a battery such as a lead-acid, or “flooded,” battery. But many new cars now come with absorbed glass mat (AGM) batteries. Some lead-acid batteries have been enhanced with advanced materials and design, but the other type, AGM batteries, use a glass mat separator to allow an electrolyte solution to move between the thin battery plates. It makes them well-suited to repeated draining and recharging.

Why are carmakers using these new and more expensive batteries? Today’s high-tech cars need more electrical power. As vehicle technology evolves, cars need more and more electric power to operate features such as today’s stop/start technology, safety and convenience features, and all the additional power outlets that charge our devices.

Not surprisingly, these enhanced batteries also come with an enhanced price tag. AGM batteries can cost between $200 and $300, twice as much as traditional lead-acid batteries, so you want to make sure you’re buying one that will last.

I can't jump other people in my car.  Freakin' battery is halfway up under the dashboard.

My Subaru has the battery behind the headlight assembly, where it can be easily jumped.

I guess that means you can't be jumped either if the battery dies?  Yikes.
