"Can eneloop be used in underwater light?
Please do not use eneloop and SANYO Ni-MH batteries on underwater
light and sealed application. SANYO Ni-MH batteries contain a gas
release vent, which allows releasing hydrogen, when the battery is
misused. For normal usage, gas will not be released but hyper-electric
discharge or short circuit can cause inside of the batteries gas pressure
to rise and gas will automatically be released. This gas contains
Hydrogen and sealed devises cannot diffuse the gas. So if there is any
firing source like sparks, it might cause bursting or fire."
I'm unclear on any difference between the eneloop or Sanyo NIMH batteries and the energizers or rayovacs I'm been using. (I have a Canon A570is that uses 2AA bats).
Anyone have any insight on using rechargables and any hazards?? ( I know the airlines dont want us to pack lithium bats in the checked baggage....).
(I also found this: http://www.cdc.gov/niosh/fact0002.html - )
PS.... yes I'm new here.... but I wanted to get this posted quickly - and I did a quick "search" but found nothing... I'll post in the Intro section in the next few days.

Some lights I have owned in the past that used NiCd batteries had a little hydrogen absorbant packet and special instructions not to charge until the unit has vented and a bunch of other warnings.
The Eneloop is probably not intended as a continuous, high discharge rate battery design, it is great for applications with high rates and then no rate such as strobes or cameras or other applications with relatively high loads and then get a rest period such as between charging the strobe capacitor or recording a CMOS chip etc.
I have a DR LED750 light, great light, I have tried various rechargeable batteries in it but frankly, Duracell Alkalines are the way to go for that light.
Not an expert on this, I think BVant could offer better info (much better).

The bottom line is go ahead, use the Eneloop type batteries but if you are at all concerned let them vent overnight.
