NOTE:
The above information, while credible, is worth what you paid for it and should not be considered gospel.
Do due diligence, research and have a H-D Field Service Manual before working on your bike.
You will probably have many opinions and suggestions presented; make sure you research the person providing the helpful information as there are some who provide good information that is useful and some who speak out of other orifices with gibberish. You will figure out this quickly.
The link below will help you find original Harley-Davidson parts.
This will lead you to the battery that H-D recommends for your bike (65989-97E). It appears to be a 17.5 AH (amp hours) AGM battery.
This link provides the OEM battery part number but no mention of CCA (cold cranking amps). AH and CCA along with the H-D battery part number #65989-97E are what is important to your search for a new battery.
Any battery Seller should be able to cross reference the H-D battery part number, for the appropriate replacement battery.
Maybe it's my phone. The H-D website for original Harley parts is not so easy to find sometimes. The attached picture is the section where I get to the "H-D OEM service parts". I have a desktop link on my laptop that goes right to it.

Maybe open one of those books that lists them, or website with drop down menu.
I have had good luck with Harley batteries but I buy fleet farm for most everything else and have good luck.
I'm partial to HD batteries from the dealer, the cast in threaded steel inserts for the bolts stay tight, I've had chronic problems with the terminals loosening on aftermarket batteries that use a bolt and nut.
That eventually leads to starting trouble and battery terminal damage when arcing occurs.
Big Crank motorcycle batteries are manufactured by East Penn Manufacturing, who make DEKA batteries (and a lot of other names). I've had good results with DEKA batteries in the past, and wouldn't hesitate to buy another one, or one of their "house brand" batteries.
I've also had good results with Yausa. Interestingly, the address of their home office is almost the same as that of East Penn...
Google says "While Harley-Davidson doesn't produce batteries, they contract with East Penn to manufacture them with the Harley-Davidson label".
