Well I noticed that the battery maintainer light was red yesterday....so I took it off the battery and tried to start....Dead. So I load tested it after I got it to charge with my 6 amp charger....no go. Time for a new one.....I guess I'll go with the Deka ETX30L 400 CCA Rating. $105.00 Delivered. Don't know how old the oem Harley battery is....it had no sticker on it ... 2 - years ago when I bought the bike. It was turning over a little slower last fall though. I guess the Deka is the same as oem.
