The answer for why is it more expensive for the f4i battery is ... it has a higher cca then the other. Sounds stupid that it costs that much more, but they figure “you need it” I guess?? It’s like my HD. battery, physically, it’s roughly the same size as yours, has way less cca ( 300vs200) yet mine is anywhere from $107-$120, and yours is $40-$50. So I’m using the f4i battery in my Harley, cause your ALWAYS better off with a higher cca as long as voltage is the same. Now after rambling on, my advice is FORGET WALLY WORLD!!! Spend the little extra $$$ Go to interstate battery. I have a actually interstate distribution store where I live, so can deal directly with them, BUT, they make an amazing battery, and I have NEVER, had an issue with warranty issues. I had a vehicle once that destroyed batteries within mnths, went through 5 batteries before I got rid of it, and never so much as a question. Never questioned dates, etc. simply took old battery, gave me new one, period! Unless you have a crappy distributor, you will have 0 issues.

Or DONT waste your money on an interstate battery and live a happier life.
Have had my F4i since 2007. 94k miles on it. Been threw a few batteries. Manage a car dealer, also have interstate wholesale. Used them because they are rebranded yuasa [the oem brand] and have always gotten the same life from them as the $40 amazon batteries I decided to try when I was broke.
