Surefire Lithium Batteries Problem With Lithium-ion Rechargeable Batteries?

Problem with Lithium-ion rechargeable batteries? - surefire lithium batteries

I bought 4 Power 3v rechargeable 123 to secure my flashlight, you can organize the first count, but sure, I was cleaning the lamp twice. I did not go back, I wonder why the bulb lights up and immediately released?
I know that the rechargeable lithium battery is infallible, and there, but they have 1000mAh written on it, and it scares me. Someone I can be educated electricity, because I do not understand clearly.
