You drank the cool aid..no turning back now. I smile ever time I hit the key on my $80 AGM Walmart battery. Now if they only sold Harleys.

 

While I understand your concern about the the charging system you could have checked that yourself with a decent (Fluke) volt ohm meter. As far as batteries I would never drop a dime on a HD branded battery. Ran an Odyssey for over 5 years and while quite happy with that I decided to try an Interstate when it died. Have ran other batteries but so far these are what I like best.

 

I need to replace the battery in my Dyna, I like savings the money and I'm considering the Big Crank, but I need to know, does HD make a black battery cover, so I don't have a light gray battery on the side of my blacked out ride?

 

I just bought a battery from battery plus. I was on my 2nd HD battery. It was dead on a Sunday morning so I went to battery plus instead of waiting for the HD shop to open Monday.
My first HD battery lasted 5 years the 2nd lasted 3-1/2 years so I will see how long the battery plus one lasts.

Why not simply use the cover that came on your bike?

 

The HD battery uses special MOCO acid than generates a special type of electricity that is required for your bikes electrics.

 

Batterys Plus also has a better warranty than HD. Here in the AZ they don't last as long so there's a good chance of getting the next battery at a pro rated price.

 

I was off to work and my bike would not fire up this morning went by fresno Harley and got a bar and shield o e m battery with one year warranty. I too wasn't sure which way I wanted to go I wanted the best possible I don't like being in the position of my shinny bike is as good as a boat anchor

 

Just got the Batterys plus Duracell, 400 cca two year warranty, Didn't want to wait for delivery. Still cheaper than HD.

 

I bought a deka from o'relies auto to to go in my fxdl 2 years ago. The original lasted 8 yrs on a tender. Installed myself and saved lots between the battery and labor.
