Comments about Quantaray Quantaray QC-4000S 6volt, 4.0 AmpHour NiMH Video Battery:
I acquired a Quantaray QC-4000S through Ritz Camera. [...]I'm a videographer. I have to have a good light to help illuminate things when the lights are low. My current batteries need to be replaced, so I searched the Web for a replacement. At [$], the price was right. Maybe that should have been my first clue, but it wasn't. The battery didn't seem to take long to charge. That should probably have been my second clue. The packaging and the website advertised the battery as a 4-hour battery. Alas! when the time came to actually use the battery, the light shone brightly for around 15 minutes. But, after that time, the battery steadily lost strength. Fortunately, I had a spare light and battery. I switched, the event was saved and I returned the battery.Did I get a bad battery? I'm not sure. [...] I would recommend calling the company and having the return policy explained, so you get it right the first time. Otherwise, it could be a painful process.
