I have bought two Harley OEM batteries in the bast 18 months. One for my Geezer Glide and one for my Wide Glide. Haven't had any problems with either one and the Geezer Glide has a 1000 watt audio system with eight speakers which I listen to when I am working on stuff in the basement.

Just my .02.

 

I've been using Batteys + Bulbs Duracell for about 8 years now, 2 year warrantee on em. Last 2 had a problem. Wife's 04 1200 Custom's battery crapped out after 11 months. Got a free replacement. My 07 Dyna's decided to die also, after 22 months. Yep, another free battery.

 

I agree, the original battery in my 2012 lasted 3 years. The second Harley battery lasted 4 years. This with no tender and cold ct winters in a un heated garage. Only reason I went with a after market battery was for more cca’s. After I increased compression on my 103 the Harley battery seemed to labor more at start up. With the few more cca I have with the yuasa my bike labor’s less at start up. Then again I keep it on the tender now, maybe that’s why.

I just replaced a 4-year old battery that I'd bought from Dennis Kirk that was starting to have a tough time starting. Always kept it on a tender, so I got decent service from it. Bought a new one from Batteries +. Don't know how long it'll last, but my '09 Low Rider never started so quickly. So far, so good, and at least if it ***** the bed in the 2-year warranty window, the store is only about 5 miles from my house.

 

The battery that came in my 2015 Low Rider made it a year and half before crapping out. And yes, it was properly charged with a battery tender. The second one lasted about as long. Thankfully, I got the second battery under warranty. Two HD factory batteries lasted me about 3 years even though bike was always garaged and batteries charged with a tender. Went with one from this company and no issues:
