I’m looking to use this to keep a set of marine batteries warm. They won’t be getting splashed but they will be in a moist air environment? Will this be an issue?

Humid environments are acceptable for any of our battery heater models. What must be avoided is situations like standing water that is common in boat compartments, or direct water spray from under-vehicle mounted RV batteries that are open to road splash and snow.
