I was reading through some posts just a while ago and started thinking about my e01 and how i miss using it since i got my ezaa. so i searched some threads on the e01 hoping to rekindle the flame for my former companion and found the thread "is the e01 still worth it". after reading through it i was so excited and went to go grab my e01 off my keys to discover the head wouldn't turn. so i applied some force and heard it pop. instantly i knew exactly what it was, a leaked alkaline. so i took the head off and discovered i had a battery stuck in my light. i've read some stories on here before about batteries leaking and ruining lights but have never had it happen to me before. i thought for sure my light was a gonner. so i grabbed my drill and put a bit through the battery and to my suprise the battery popped right out. the battery is still hising at me as i type. i'm just so happy i didn't loose my e01 i had to tell someone. i never really thought it would happen to me because i only use name brand batteries. the battery in the light was an energizer industrial. well, lesson learned, never ever will i leave alkalines in any of my lights again.
