I use these batteries in my front strobe light on my bicycle. I have 2 sets of rechargeable batteries that I swap out almost daily after a 2 hour ride. One set of batteries by another brand are 1000mAh and these are 1100mAh. Let me tell ya these work noticeably better, are brighter and last longer. I'm not sure if the difference in brand or the extra 100mAh, but if I were to purchase any more, I would definitely choose these. I can easily see the difference.
