I have a nearly new battery in my boat. I believe its only a few months old. Anyways I started having problems. i would charge it up 100% only for it to be dead the next day. I had to jump my boat several times with a booster pack while on the water. After jumping it I would cruise for say 20 minutes and it would start back up fine. I took it ot NAPA and they said the battery was "good". At first i thought maybe something was pulling juice so I charged up up 100% today. Started the boat just fine. After running say 10 minutes I shut it off. Started it back up again but it was pretty reluctant. I again let it run for a bit... With the boat still running I unscrewed the quick connect to the + and the engine still ran fine. Killed the engine with the battery still disconnected went back a hour later and hooked the battery back up. When I tried to start it again all I would get is a very slow turn over but no start. Hooked the booster pack back up and it started up just fine. As mentioned its a new battery from NAPA and tehy said it tested good. With that said they hooked it up to the charger for a hour then straight to the battery tester. Can you think of any other possible issues that could be causing this or is NAPA just trying to get out of replacing a battery?
