That sounds like their TX30LA battery AGM. Made for them under the original DEKA #EXT30LA. DEKA makes the same battery for many private names. They also make the Harley batteries, but to their specs.
You can buy the same battery from them direct at Federal Batteries for around $119, but locally I only find it from about $128-$138. The original warranty is 1yr limited, but some places only offer a 6mo or even as low as 90day.
NAPA is 1yr. Better to buy at a local to you store anyway.
Good to hear you are having good luck with yours.
Ride Safe !
