Task: Sentiment Analysis
Input (English): The battery I got has a terrible quality. With a full charge over night (~8 hours), the battery only sustained my SD800 IS camera less than 12 hours normal usage, shot around 20 pictures. Versus to the original battery pack with the camera, the original battery can last over two days normal usage, shot around > 100 pictures. I believe the vendor selling degraded products.
Output (English): Negative
