Just finished a job where I swapped out a standard 12V battery for a deep cycle marine type
The old battery in a rural Montana cabin system kept failing after 8 months, but the new one has lasted over two years through power cuts. It handles the constant small draws from the panel and radio much better. Anyone else made this switch for remote sites?

That's a solid move for a cabin setup. Deep cycle batteries are built for that exact kind of slow, steady drain from lights and radios. A regular car battery just gets wrecked by it, it wants a big fast jolt to start an engine. Makes total sense why yours gave up after a few months. The marine type is the right tool for the job, glad it's working out for you.

lindaburns has a point but I've seen the opposite happen. Marine batteries can be overkill and cost twice as much for a simple cabin radio. A good quality regular battery with a small solar maintainer often lasts just as long if you don't drain it too low.
