You are dead wrong. I tried this last year, saved $50 on the battery and had to spend $550 on a new EHC and a new battery.I disagree.
Harley does not make batteries. Harley primarily uses Deka Batteries. You can get them under dozens of names. Just look for made by Penn manufacturing on the back label. You will pay a lot more for the Harley sticker on it.
Furthermore, there is nothing all that special about them. Just about any AGM over 300cca will do fine.
O'Reilly sells Deka 20lb batteries (with their label). Usually about $105 and you can usually buy them 'online' and store pickup and get 20% off.
