Task: Sentiment Analysis
Input (English): I purchased this battery as a backup for a vacation. It works perfectly. It is indistinguishable from the battery that came with the camera, lasts just as long (one or two days of frequent use), and charges fairly quickly in the standard charger. For folks going on a trip, I recommend taking two batteries for your camera. Just slip the spare into your pocket (not with your loose change or car keys, though) and pop it in when the camera needs it. Charging took a few hours overnight. For European current, my standard charger (not incl) said it takes the local voltage, so I only needed a plug adapter.
Output (English): Positive
