Subject title says it all. After charging the battery for the first time, I fired up the camcorder, and it registered 392 available battery minutes (with the LCD display on).My existing Sony brand battery which is several years old still holds around 450 minutes per charge (with LCD), so this battery doesn't quite reach that level, but it's close enough for government work. Given the wide price disparity between this after market item and its Sony brand equivalent, it's a reasonable sacrifice to keep more than a few dollars in your pocket.I'd definitely recommend this product. Good price, good quality, good value.
