I took out my charger from my boat and installed large alligator clips on the ends of the wires. After the last few fishing trips, I noticed that the batteries weren't fully charged in the morning. They are brand new lead acid batteries.
I have been fishing local electric-only motor Lakes, so the batteries were well used. I just don't remember ever taking more than overnight to charge them.
Do you think it's the alligator clips or just that the batteries were very worn down?
