I just replaced my 4 golf cart batteries and my boat has an old Heart inverter/charger Link 2000 set up that seems to have worked flawlessly for the 13 years I have owned her. The boat is on the hard and when I attempted to charge them using AC power, it took longer than I expected to go from Charge to Accept and never went to Float. The cold volts reading on the Link is 12.35 V while a direct reading on the batteries with my multimeter gets 12.64 V. At the same time, my starting battery (a wet cell 12 V) matches exactly and it has a much longer wire run to the Link unit. My boat lives on a mooring all Summer so all future charging will be via alternator until next Fall. I have already reprogrammed the unit to make up for the "gotcha" bug discussed here previously. I don't want to harm my new batteries with incomplete or inaccurate charging. To those smarter than me, does this sound like simply a bad or undersized sensing wire? Is there an easy test for this? All wires disappear into dark places and before I start down this path, I wanted to see if there might be another answer. Thanks in advance for any guidance.

Brian I wouldn't suspect an undersized sense, after all it's measuring voltage with virtually no current flow to eat up voltage. If I could, knowing zero about the Link and any oddities, I'd likely start with my meter on the sense, disconnected from the link. On both sense wires just for verification.

Brian, we have the Link 2000-R but I'm not aware of the 'gotcha' bug you refer too!
Can you point me to it?
