Not knowing how many salesmen were demonstrating my Wing's stereo in the dealership showroom or the previous owners 4 months of ownership without using a battery tender... When I turn my ignition key on, the volt meter beeps (low voltage) and shows 11.2 volts. My Wing starts right, but takes 6-8 seconds of running on high idle warm up before the volt meter shows it's 13.8 volts. Also. I get home from a ride, let the Wing cool down 2-3 hours and then plug in my Battery Tender. The Battery Tender goes into charge mode (red light) for about and hour or so before the green light on the BT comes on? Does this sound like my battery is not going to last too much longer?
