Help!
When do lipos go bad?

I made this video to show you what the group of bad lipos did to the sound of the motor before cutting out. These Lipos have not been charged or used since October of 2011. This was due to work related issues. I balanced and charged each battery tonight before going flying to discover why the plane would cut out in mid flight. This test is conducted after that encounter.
Question is.
Is it time to get new lipos for the stock motor of this um?
Is there a way to fix these lipos?
Could it be the charger/balancer?
Feel free to comment and offer good suggestions for replacement batteries if that is the case.

Batteries used are Eflite 3.7 150 mah 12c- Hyperion 1s 3.7v 25c 160 mah
