YES, All Good Tips above. 'Battery Tender' is a good choice.
I have always kept my battery on a 'BT' during the off season and times of not riding the Bike at least once a week.
I do a battery load test at the start of a New Season. I had batteries that last 5+ years. For my Spyder, I will probably change it out at the 5 year mark.
My 2 cents. .....
