Bought a brand new Interstate 24F from Costco today for my Odyssey. Got it home and immediately threw a Battery Tender on it to "top it off". I did the same thing two weeks ago for my Mazda which also just got a brand new battery. Am I being too OCD or is this a good practice assuming the batteries might be sitting without a float charge for a month or so? I don't drive long trips at least with my car so I wanted to be sure the battery had a good start on life.
