There is nothing more aggravating than hitting the starter button and hearing nothing. I've heard that sound more than I care to so my Honda had a battery tender. I got one for my Nomad. They're around $22 and worth it. They keep the battery conditioned and fully charged.
There is a fused battery connection under the seat. I used it to connect the battery tender.
I placed the receptacle in an easily accessible location. That's all there is to it.
