The battery in my fifth wheel is over four years old. Should I consider replacing it based on its age? It has been used almost constantly during this time. Thanks, Jim
Since you said battery (not batterIES), I assume you are typically in RV parks with power, don't sweat it. Worst case, you can plug in to get the slides in/out and pick up a battery when you get around to it.
If the converter is keeping it fully charged and not over charged, the battery will last a long time.
