"These 6000mAh 21700 batteries are just great! They last longer than the others and they are down right reliable. I've bought several now and I use them in my flashlights that take the 21700 battery. Even on the brightest setting, the flashlights last a long time with these new 6000 mAh batteries. They charge up in about the same amount of time that it takes for the 5000 mAh batteries but they do last longer. I'll go for more power every time. These batteries are the BEST!"
