I was using the Battery Tender Jr.
I checked the voltage after hours of charging and it was still at 4 volts. I decided I was done waiting and went out and bought a new battery. An hour later, I was cruising the highways on the bike. =)



Well, that will work

A BT Jr isn't a charger and won't charge a seriously discharged battery. A true smart charger might bring back a neglected AGM.
