Hi all. I'm sure that this subject has been discussed numerous times, but it would be great if someone in the know could add to my meagre knowledge of same.
As i understand it, all batteries or cells produce hydrogen gas [ herein, h ] as a byproduct of use or storage to a greater or lesser extent. OK, not normally an issue in normal day to day use, but whatabout in sealed torches, like high end professional and tactical ones, that we're all very fond of?!
eg; Could a 2xAA cell IPX8 rated LED torch produce enough h in an hour of use to create an explosive situation from switch contact arcing ?
Is there a standard that requires switches to be isolated from battery chambers in IPX8 or higher rated torches ?
Does Li-ion chemistry create a similar scenario?
Is this all just hot air, or a valid point?
It all may be irrelevant, but i would be interested to know?
Lots of thanks for your thoughts. :thumbsup:
