Query: Won't charge completely, light never turned green on charger.

Won't charge completely even the first time charging them, light never turned green on charger even after charging for 15 hours. [UPDATE: Customer service was responsive and replacements came promptly, though I did ended up having to get regular non-rechargeable AA's during the wait at a local store because I needed some right away. I guess I was just unlucky to get a bad batch.]
