Li-ion,Li-Poly overcurrent protection PTC Fuse usage consideration

[Danesh_SA]

Hi all,
I want to use 1206 1.0A PTC fuse in my design to protect both battery and circuit from short circuit.the device is portable and i use linear Li-ion battery charger (MCP73831) ,i just one to series PTC fuse with battery .
the question is:
-is it a good option for protection?
-where should i place PTC fuse in my design?(just after battery conector on my PCB?)
-a PTC fuse works for my protection condition or one time fuse or fusible resistor?

Thanks!
