Recommended 1992 Seca II Battery?

[trapline]

Im getting a 1992 Seca II and it needs a new battery is what I am told. along with carbs cleaned. Im having a mobile mechanic come out and he asked me to pick up the battery. Where do I go and what do I get? I guess price isn't really and issue? I heard battery tenders are good so ill probably untimely get one of those. I plan on commuting on it 2 days a week plus. For my truck I would go to auto zone and ask for the middle range one does the same apply here?
