Having let the boat sit for over a year+ .. When I charge the batts using the onboard charger, even after getting a green led then three, four days later, start charging again, almost full bank of red leds, takes all night to go green again.
Interstate batteries, 4 years old.
Motor starts fine, spins fast. still.. kinds tough to spend another 200 on batteries dang it. But with a trip planned, better safe than sorry? anyone seen this charging behavior ? I have to admit I kinda know its not right.

try topping them off with a standard charger, then let them sit overnight , then hook the onboard charger to them and see if anything changes. i would also top off the water in them after using the standard charger.
btw im no expert on batteries but in 9 years of boat ownership i have had pretty good LUCK with batteries. now catching fish is another story......

I wouldn't expect them to be good, about 3 to 4 year's is it for an average batter and letting them sit is hard on them.
My thoughts are buy fresh batteries at the store, by as cheap" as you can and replace often... 3 to 4 year's

Go to Harbor Freight and pick up a resistive load tester for around $12. Charge your batteries for 24 hours, let rest for 24 hours, then load test. If the needle doesn't stay in the green, you have a bad battery, probably a weak cell drawing down the others. You can do better than Interstate batteries.

how's the water level in the batteries? dry cell will make the battery not charge.

For what it's worth, I manage to get pretty good use out of my batteries after following advice I got here on TFF years ago.
Like most of you I have an on-board charger, but rather than plugging it straight into a wall outlet, I have it plugged into a garden timer that only comes on for 1.5 hours each day. I was eating through batteries pretty quickly even when they were connected to a nice Dual Pro charger that supposedly dropped the charge to nil when the batteries were topped off. I got 6 years out of my last set of Interstate greenies using the 1.5 hour a day charge cycle time.

thanks for replies! Battery's held up fine thus weekend... but I am pretty sure carbs are needed some love.. would bog and quit trying to hit 2500-3K rpm. Changed fuel line, its fresh gas, but I suppose there is too much internal build up of gunk. I have zero boat fixing money too, lol.

get a small gas can and dump a can of seafoam in a gallon of gas and hook the fuel line directly to the can. run on muffs. could possibly help and wont hurt any worse than it is.
fyi: add oil to gas too if you premix
