I cant find tread on where to buy Batteries. I know there were two places linked
that had decent deals, thought I had them saved. Not buying a HD brand.

 

I use Interstate I like the cranking power and the warranty.

 

I have an HD in my Softail and put a Napa one in my wife's Softail. Happy with both.

 

Walmart if they have your size. Have one for my Softail. Last about a year less than a Harley mothership one and 1/3 the price. And you get a replacement most anywhere 24/7. Mine can sit couple months without maintenance charge. Any longer and it will need it. So the reserve amperage is fine.

 

Look at the Deka wed page; they make the Harley battery. You can get the equivalent battery for about $70-80 less than Harley

 

I've been buying my batteries from Battery Mart.
Good price and they deliver right to my front door.

 

I have a 2014 Trike and installed (4/2018) a Deka Sports Power ETX-30L. $109.00
Good battery, check out the spec's.

 

Yuasa makes a great battery for the price. Recently replaced the original battery in my Road King with one.

 

That is what I've used. Link to some HERE. I used the Premium.
