Good Deal. I would still keep it on a tender if you can.

Get a tender anyway

No, I didn't leave the bike on in any fashion, checked all the connections and everything was clean and tight. Any input would be appreciated.

AGM on car with tender in play, about 3 years. Hence battery should charge up to 13.7, but even with the tender on the car when not driving it, will start to see the fully charge point voltage start to drop out.

AGM on Harley, all depends on if you are keeping the battery on a tender when not riding it instead. Hence full charge will start off around 13 volts, but each year, full charge will start to drop instead. As for what really kills the AGM in the bikes, the battery is not being charged at idle, but in a drain start from the running lights instead. Hence AGM has to be seeing 14.1 volts to start charging and if you put a volt meter on your system at idle, will not be up to 14.1 charging volts.

Truth is, when first starting to ride my bike as the engine is warming up, will try to stay in one higher gear then normal, to keep the charging/working voltage up to 14.1 from the initial starting battery draw to get the battery topped off again. Same goes for when stuck in stop and go traffic as well, since again, charging voltage does not come up to 14.1 volts until your about 1.5K rpms. So what is really killing the AGM, is all the drain down states, and most of the time if you are just lugging the motor, charging system not charging up the battery to full charge state instead. Also, throw in the new security systems on the bike that is still draining down the battery when you shut the bike off, and not surprised to see a battery cooked in a year of less is not kept on a tender when you are not riding it for a few days.

One last thing, and make sure that the tender you get, is for the battery type you have. You stick a cheap lead cell tender on a AGM battery, and it going to kill the battery in a few months. Hence it will not having the needed charging voltage to begin with, nor enough amperage to bring the agm battery back up to a full charge to start before it kicks over to just its maintain cycle state there on out.
