Bests & Worsts Reviews from Amazon

I've purchased surefire batteries in the past and they all worked flawlessly. If you are using these batteries for your battle lights, it's important that these batteries function right out of the box. On my second purchase a few weeks ago, I had (04) batteries dead right out of the box. I have (06) new batteries left but I have not tested them for power. I still think surefire batteries are the best, but I would buy directly from surefire next time. Amazon gave me a full refund for my order and I will commend their excellent customer service. If you have to buy from Amazon, test the batteries when you get your package. At least Amazon will give you a refund if you dead on arrival units.
