I found Pelican's bulletin regarding use of batteries. No surprise, but they don't approve Surefire...hmmm perhaps its the competition? If someone else posted this before, I applogize. I searched CPF for 30 minutes and couldn't find it.
Highlights from bulletin:
Lithium batteries can explode, leak or cause
burns if not handled appropriately. Please
observe the following rules of thumb:
• Use only Panasonic™, Energizer™, Duracell™, or Sanyo™ cells
• Do not mix with used or other battery types/brands• Replace all cells at the same time
• Do not open batteries
• Do not dispose of in fire
• Do not heat above 75C (167F)
• Do not expose contents to water
• Do not recharge
• Do not install backwards
On another note.. I work as an Engineer and was meeting with a salesperson for an industrial wireless monitor that happens to use 2x123A primaries. Of couse I inspected them and saw they used Panisonic cells. When I asked about user battery replacement, they explained that because of potential vibration at some installations they solder the batteries in place so they don't have any intermmittent contact probelms. I expressed my concern about soldering and potentially blocking vent holes because Lithium batteries can somtimes explode and that loose batteries are actually banned from commercial flights.
Of course I got some questions from the salesperson and my boss as to why I knew so much about batteries, I just explained it was for some "hobby" interrest that I have. I couldn't come out of the closet that I'm a flashaholic.
One week later, I met with a more technical person from the same company, and he mentioned that it had gotten back to him about me knowing a lot about lithium batteries and raised some safety concerns.
I guess all my time spent at work at CPF wasn't a complete waste!
