Is there any batter app which alerts me when the battery is full with loud ringtone or a custom ringtone? I tried some battery apps but they have very low volume ringtones and some of them don't allow me to select custom ringtone.
I loaded that on my Ativ S 2 years ago and still using it today.I use "Battery" by Arthur Semenov. It does what you want + a lot more and has a great Live Tile. In the US Store it is the first result when searching the store for battery.
