A battery monitor as an example considers a battery fully charged when the current is less than 2% of bank size. Your charger is smaller than that 2%.
After a day of sailing it typically took no more than a few hours to charge. With that being said the only instrument I am using is my depth sounder. Now with a stereo installed I may need to up my charger to something a little bigger.
