Can any of you battery experts shed some light on the warnings provided by Eneloop not to use their batteries in waterproof lights? My friend recently asked me this question. What are the chances of anything actually happening in a Fenix, Olight or ITP light. He wasn't asking about a dive light, just a standard IPX8 handheld light
Quote from Eneloop:
Can eneloop be used in Underwater Lamps?
No. Do not use it in equipment that must be air-tight.
Such applications do not have a function to stop the discharge
of electricity, and when more than one battery is
used, it may cause the batteries to over-discharge. This
in turn can trigger the generation of hydrogen gas inside
of the battery, and since air-tight equipment
is designed to prevent gas from being diffused,
the contaminated gas may cause an
explosion when the equipment is switched
Thanks in advance
