Good advice!
Interstate batteries are high cost, and are living on their old reputation, which they no longer deserve.
I go to Walmart and buy the biggest, highest amp battery that will fit in the battery box.
Then: I keep a Battery Tender, or Battery minder connected, whenever I expect to not use the machine/vehicle for more than a week.
I think a lost of Interstate batteries are sold by mechanics because they get a higher profit margin. Optima is another brand that ain't what it used to be.
