Good point ChiffaN. Didn't know that. I hardly ever let mine get below 20%.
Updating my earlier post where I mentioned the "Accura" app. After the update that was supposed to fix the 0% battery health, my iTouch still registers 0%.
#Accurafail as the tweet would go....
Thanks Ron. I'll steer clear of Accura.
O.K. I just downloaded the latest update to Accura (vers. 3.2- Feb 10th) It at least gives me a reasonable result when I check battery health (100% for a virtually new iTouch 3g 32 gb- as opposed to 0% before update). It has always seemed to match the iPods 20% warning level when I used the "estimated battery health" slider. Is it accurate? The million dollar question! The jury is still out on that one. If i can help answer the question I will post it here....

A very detailed thread (it has a guide to test for defective batteries):
