If the ends of the battery are bulged,I would think the battery is toast. Only reason I ask is that it will get 12.8 on full charge,green light is on. Go to 2amp,will not go green.It's too bad ,picked this up at a closing of a customer which I bought this new for ,not 2 years ago. When it's off charge the meter reads 12.2 volts. Just clicks like a bad ground or bad terminal connection.Swapped with the other battery to see if it was a cable thing,fired right up.
Surprised it's a nautilus 730ca,160 reserve.
I'm thinking the battery was mis charged,the water levels are good. Any ideas,or just trash.Thanks guys in advance.
