I plug mine in from time to time thru the off season to keep them topped off, but noticed the other day that after 24 hours of charge there were a few charge lights left still on.

Im sure my batteries are due to be replaced but dont want to fry a new set. Espeacilly cause im considering optima batteries this time around.

Any input is appreciated.

I had one that caused the batteries to need water about every month and a half or so. I waited until I knew it had been fully charged for more than six hours and felt the batteries. They were still as warm as when doing a full charge so I disconnected and replaced it. Now that's my check when I can. My batteries are cool if the chargers have indicated a full charge for more than a few hours. I'm not around my boat for good stretches, so I try to get my batteries charged before I leave, then turn off the chargers. I'd be different of I could check it every week or so.
