I assume the batteries are the original ones that came in cart (2005).

I use a PowerDrive 2 charger that came with cart. I hook it up after every round of golf and verify that it starts, but I never stay until finished so I can't say how long it charges.

I checked all the connections in the battery area and all appear clean and tight. Not sure what you mean by two "large" cables. All cables that I saw appeared to be the same size.
