I recently purchased a SureFire LX2 as a self-defense tool and was head over heels in love with it until I came across this forum which wised me up to the real dangers of the 123A cells it takes. After reading extensively on the safety of these batteries and viewing some really sobering photos, I've decided that it simply isn't worth the risk of a fire or explosion, especially since I planned on keeping right next to my head while I was sleeping.
So, I'm returning the LX2 to where I bought it and am now looking for a safer flashlight with comparable output. I'm looking at the Fenix LD10 or LD20 now. But with all of the new information I've ingested regarding reverse charging, venting, highly toxic gasses, etc., I'm having a hard time sorting through what applies to standard alkaline batteries and what is specific to the lithium batteries.
My specific questions are as follows:
- Are standard, everyday AA alkaline batteries capable of producing the potentially violent explosions that the 123A can?
- If the AA's do leak, is the material as hazardous as the 123's?
- Do the AA's vent gases? If they do, would it build up as much pressure inside a flashlight as the 123's to the point where it essentially becomes a pipe bomb?
- Is it likely for an AA battery to explode or catch fire if dropped or impacted?
- If reverse charging does occur with an AA battery, would it result in the same consequences as the 123A battery?
I know those are a lot of questions, but I want to be sure the chunk of metal filled with energy that I put next to me when I sleep is absolutely safe.
Thanks so much - although this is my first post, I can't tell you how great of a resource CPF has been for me during the past month.
