Our good colleague at Wetpixel, Adam Hanlon, recently reported that the extremely popular Eneloop rechargeable batteries are now not recommended for underwater strobe use. Panasonic, who owns Eneloop, specifically states on its website "Please do not use Eneloop Ni-MH batteries in underwater lights or other airtight appliances." Adam mentions it could be interesting if the strobe manufacturers have something to say, otherwise we’ll all keep using Eneloops as usual. It could indeed.
