Places like Revzilla, Dennis Kirk, J&P and Parts Giant sell them.

You will get many opinions on batteries. The link below will give you most all you need on "best" batteries.

Yuasa is a good battery; my son is an engineer at the Yuasa Plant in Reading, PA.
I have been using Big Crank Batteries for 10 years or so on my Harley's and metric bikes when they needed to be replaced. Reasonable Prices and they seem to hold up well. Free Shipping in a timely manner.

They used to but I have no idea who actually made the batteries. After the stock battery died after 4 years on my 17 Slim I bought the Harley branded lithium (this was right before I stored the bike for the winter). Parts guy at my local dealership gave me crap instructions on maintaining it and it was flat out dead when I went to start it in the spring. The dealership let me return it/gave me a full refund.
I never bought a lithium battery for my bikes again.
Aside from the stock battery in my old Slim, Ive had trouble with OEM batteries and only buy aftermarket AGMs.

They used to, don't know if they still do.
The reason I know is that I was going to buy one from them a while back, but the HD guy on the phone absolutely refused to give me their CCA. I went with Antigravity and was just as pleased as punch.

Probably a Chineseum "lithium" battery. Lucky it didn't catch on fire.
I paid the big bucks for EarthX LiFePO4 Group 20 for the same cranking power as the Group 30 in the touring frame. Cause both softail and touring have the same size engines to start! Jamming a little battery into the softail frame makes for marginal starting and early battery death.
EarthX is assembled in USA, dunno if the cells are made here or in China. But it's lasted a couple years and never fails to start my 117 M8. Earth X told me to charge it prior to winter storage then disconnect (I pull main fuse since batter is hard to access to disconnect). It stays mostly charged overwinter, I top it off in spring and go.

My 3 year old Advanblack LIFEPO4 just crapped out on me.
I removed the battey 2 months ago, was sitting in my house the whole time.
Put it on the charger and it showed 13.4v, on the the BMS screen, installed on bike, hit start, nothing. Nothing on the BMS screen.
Put it back on the charger, shows 13.4v, installed again, nothing.
Pretty sure it's toast.
