Not ready to go lithium but that’s a lot of crank! Compression is set at 10.2 on my 103 and it has acr’s. It’s just time for a new battery. I thought I might go with a little more cranking amps. The Harley battery is a little sluggish sometimes. Thinking maybe a Yuasa. I remember tin cup spoke highly of that brand.

Ive always had good luck with Deka. The one in my John Deere has a mfg date of 1998, still cranking.

My Duracell from Batteries Plus is starting it's fourth season next month. I think it's made by the same company that makes HD OEM units.

Ordered the Yuasa with a new tender. $136 bucks total from 2wheel. A new battery from the dealer goes for $130. Thanks for all the good suggestions.i did get 3 years out of the first Harley battery and 4 out of the second. This without a tender. I Can’t complain ( but sometimes I still do)!!

I have the same Yuasa in mine. Its about 3.5 years old now, and cranks it as fast as ever. My bike lives outside under a carport in the heat and cold, and has never seen a battery tender. It's never gone for more than a week or so without being ridden though, either. You'll be amazed how fast it cranks over compared to the stock battery.
