I have a Samsung Charge, and was able to disable the annoying "Battery Full" notification by using [Tasker](https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm&hl=en).  As others have stated, the Tasker solution I used is not specific to disabling only the BatteryFull notification when reached, but it *does* limit the amount of time notifications are disabled and when.  What I did with Tasker:

1. Contexts-Power, Time between 11p-6a, Battery between 99-100% ...Task - disable notification
2. Contexts - Power, Time between 11p-6a, Battery Full ... Task - enable notification.

This should limit the amount of time notifications are disabled to only a few minutes, since it only takes that long to charge the battery from 99 to 100%.
