Unless you buy 3V LI primary batteries in bulk...rechargeable LI's are a cheaper long term investment.
BUT...there are protected and non protected LI rechargeables...I've had both types explode,even the protected cells are not 100% safe as I found out one day a few months ago.
I had just taken 2 (protected) type 3V rechargeables off the charger and popped them in my O-Light.
Stuck it in my front pants pocket and forgot about it.
About an hour later I was talking to a coworker when he noticed my pants were smoking...
I looked down,grabbed the O-Light out of my pocket and threw it into my bosses office where it instantly exploded under his desk like a small hand grenade.
Almost blew his shoes off...not to mention the horrible odor of swamp gas that permeated the room...he definitely needed a change of underwear in a bad way.
He lost his glasses in the confusion...well...er...maybe they were blown off...he couldn't remember much right after the explosion because my coworker was screaming call EMS at the top of his lungs making my boss think he was fatally injured,along with being deaf and blind.
Meanwhile,being uninjured,I was searching for my trusty Nikon digital camera to video the carnage for the insurance company...just as I entered the room,camera in hand,a fire broke out under his desk and my coworker proceeded to hose down the desk and my boss with a huge (20 pounder) ABC fire extinguisher that was hanging on the wall.
Nope...I'm not making this up...it happened pretty much in the order I described it.
Next thing I knew some secretary had called the fire department and EMS. The parking lot now had Bomb Squad LEO's,two fire trucks and an EMS crew with a stretcher heading into the corporate office to give medical aid to the casualties...aka...my boss.
The bomb squad bought the story of a random lightning strike from the two eyewitnesses ( my coworker and myself ) they weren't real happy about it...but,hey...we were the only eye witnesses,so what could they do ?
Anyway...it worked out well for me...I got my bosses office with a terrific view and he demanded a new office in the basement with no windows and rubber carpet.
Fast thinking on my part wouldn't you agree ?
My first gut instinct was to throw any potential hazardous flashlights or exploding devices directly into the nearest expendable supervisors office.
Remember that...next time you are faced with explosive batteries...quick thinking could save your life.
BTW: My boss is now proud to be a lightening strike survivor...he brags about it to anyone who will listen.
