I thought my order was for just four batteries and was surprised to open the box and find 4 small flashlights with those batteries in them instead of just the batteries themselves. The flashlights are strong for their size so if I don't use them they will make nice gifts I think your batteries are tge best and as an extreme flashlight collector I've had to buy quite a variety of batteries - some good, some mediocre and some just complete junk. Yours are great! I'll be buying more of them from you in the future. Just don't send them to me inside of flashlights again, OK? Thanks and Happy New Year from Las Vegas

My father has been looking for these for almost a decade. He used to work for a company named Sattler Corp, and they would have a bunch of these Ultrafire batteries for their employees to use. It lasted almost an entire 8-hour shift with their workers’ high-usage rate. My brother and I looked for years after he left the company no success. Then I happen to Google about a month ago just to see, and wala! Ordered it to see if it was the ones he used then and they are indeed the ones. One of if not the best lithium batteries/battery brand in my and my father’s opinion.

Thanks for the bonus!
