Top critical review
on July 7, 2013
These batteries were cheap, but I figured I'd still be ahead of buying the name brand ones even if half were bad. I've used most of them now and probably more than half die in a very short time. My main use for them is in a heart rate monitor that I use for exercise. Not a big deal if the batteries dies during an exercise session, I thought, but in practice I find it really irritating. A dying battery might mess up 2 or 3 sessions, because the monitor's performance becomes erratic before it fails. I'm swearing off these product that may or may not work because the cost savings is not worth the aggravation.
