CR-123 Batteries Can Explode

Dad always said “You get what you pay for.” Sometimes, though, you get more than you bargained for.

Keeping lasers and white lights fed with CR-123 batteries tends to be expensive, so it is understandable that people try to find the cheapest batteries possible to use.  The problem is inferior batteries can overheat, catch fire, and even explode.

Massad Ayoob describes the problem on his blog, and even includes photos of a Glock damaged by batteries that exploded inside an Insight M6X laser/white light that was mounted on same.  He even has photos of the injured hand and damaged clothing of the poor guy wearing the Glock when the batteries went ‘boom.’
