| It also depends on your battery size; what size are yours? I have a 16.5 ft Tracker with an 80 lb Terrova w/iPilot and two Group 30 AGMs. I can usually go 2-3 days under those conditions before my batteries are spent (although I charge them after every outing anyway 'cause its best for the batteries). The larger batteries will give you more time before depletion. But from what you said, your batteries do seem to be sub-par. Make sure your charger is doing its job correctly, too.
It may be just one battery that's bad, too. You can take your boat to an AutoZone or other parts store and they can check your batteries for you with their battery tester. | |
