Hey guys, new here and in South Dakota. In the process of picking up a maintainer for my car. I'm browsing the Battery Tender website and they have a plug that goes into the OBDII connection inside the car. I guess in newer cars (not sure how new) can charge the battery through that connection. Has anyone seen this? Does that seem like a safe option? I have never had to store a car before, just motorcycles.
