My 2011 Forester got a new battery (under warranty) when I went in for regular service after about 2 years. The replacement lasted until the fall of 2018 (probably still okay, but 5 years is puching it. Replaced it with an AGM battery. So far, no problems.
My biggest battery problem is driving with lights on during the day (MA law for rainy/snowing weather) and forgetting to shut them off when I get home (in daylight) while leaving the key in the ignition. Next morning, dead as a doornail! Fortunately, my battery charger only takes 10 or 15 minutes to get a dead battery up enough to start the engine, and my shortest drive is long enough to fully charge the battery (and dry out the original exhaust system).
