With my smart charger (actually a 1.5 amp maintainer), I can charge the battery until the charger shows fully charged, then later hook up the charger again and it will show charging for up to 30 minutes. Since the charger senses overvoltage to tell when the battery is charged, once the battery has a chance to 'normalize' after charging, the battery voltage will be a little less than the cutoff for the charger, so it will show charging again. This is normal for a smart charger even if the battery is good.

However, if your battery sat dead over the winter, there is a chance that it is bad. I would charge it, ride it for a while, let it sit over night, and see if it starts in the morning without the starter sounding bogged down, as a first test.
