Query: Great but do not work for all sizes they state on packaging.

I got the batteries to replace the ones in my reading light for night reading. They work great and lasted over a month so far. I fall asleep with the light on, so I use more battery life than many people.Later I found out my grandson's needed some of these batteries. I was so happy to replace the batteries for (LR1130 listed on the packaging) in my grandson's storybook. But they did NOT work. I could not figure it out until I looked at the old battery and the new battery. The old battery was thinner. The new batteries was too THICK! You learn something every day. So now I have to figure out how you know the thickness to buy the correct ones.I would buy from this company again.
