H-D AGM Original Equipment Battery is rated 2.3 out of 5 by 28.
Rated 2 out of 5 by from 50/50 First one lasted 6 years of daily use, no tender. Bought another in May '14 and could not believe the price hike. I replaced it today after 32 months and it's been screwing with me for a couple months. Held voltage but no cranking amps. Was tendered most of the time. Moved to FL 18 months ago and folks tell me the heat kills batteries down here at the 24 month mark. Went with Vato Zone battery, saved 60 bucks, we'll see if I get 32 months from this mfg. 170 usd is a bit much imo, even for Mother Harley.

Rated 5 out of 5 by from Best AGM for HD as far as I'm Concerned Here's the deal, all I see is negative reviews on this battery but let me tell you my history with all HD batteries. My 1997 FLHR came from factory with a conventional lead acid battery, In 2002 I decided to replace it with a new AGM (66010-97). That's right 5 years on the conventional and it was still cranking hard, just wanted a more maintenance free battery. So here we are in 2016 and guess what the AGM just failed. Oh yes that's right 14 years on the AGM. Still held voltage but cranking amps were kaput. My secret, "battery always on a TENDER when not riding". The tender of choice Deltrans Battery Tender Plus. Let me add that I live in Canada and the bike is parked all winter. So for those of you considering the AGM go for it you won't be disappointed as long as you care for it correctly, that's the secret and the advice given to me by the service manager when I first made the change. So I will provide you with an update in another 14 years on the performance of the current one.

Rated 5 out of 5 by from pricey It seems to be a good battery but it comes with a hefty price tag. So far it's been good.
