Kman isn't your 09 still under warranty? The two year motorcycle warranty covers your battery, free replacement including labor. The battery should be still be good as young as it is, if the AGM battery goes below 4.6 volts the tenders will not charge them, you must take a fixed rate charger like a 10 amp auto charger and get a charge into the battery above what is needed to let the tender take over, about two hours then put your battery tender on it and it should finish off the charge. If you need a new battery I recommend looking around your area for someone selling Odyssey Batteries, they are a good AGM sealed battery, I sell for $132.91 (touring model) and they have a full two year replacement over the counter, unlike the HD battery with only a 6 month over the counter replacement. Good luck.
