| Thanks to miniman and the other posters for useful precautions!!!.
I think something else is going on here. Heck, we've all used alkaline and NiCd batteries for years without this overheating thing happening. At least to me, what do i know.
But flashes require a lot of power, and if one is taking pictures rapidly, heat can build up.
My new Metz 48 manual says that if one takes 15 flashes in rapid succession, one must wait at least 10 minutes for things to cool down.
Does anyone practice this? retorical question. Power usage by all our electronic gadgets is going up and up. Heat can melt solder connections inside the batteries as well as outside as our OP just reported. looks like we really need to slow down flash shots if the equipment is not industrial quality.
BTW, i've bought the cheap batteries that COSTCO sells at a good price, AA primarily. I've lost a few AA flashlights when i opened up and found the outside shells of these batteries to be ruptured and the leakage ruined the container.. never found this before on name brand batteries. Don't store things for extended periods without occasional battery checks, or make sure you use only the best quality batteries for items rarely used.
