Your surmise is correct, corrosion in those fusible links is usually from acid fumes going overboard from the battery vents. The simplest preventative is some activated charcoal pads (the kind used for soldering stations) on top of the vents, but the real question is why your batteries are outgassing enough to cause a problem. That whole situation isn't normal. I've used Wally batteries in my Nissans, Hyundais, and Hondas for ages and never had a situation like that. The few I've seen in customer cars were always from batteries pushed beyond their useful life or overcharging for some reason. On a '15 Rogue, with the ECM in direct control of the alternator (not indirect through the IPDM like most other models), I'd say the two most likely culprits are a bad battery Current Sensor or a ground issue, either the main engine grounds or the ECM grounds.
