Is this dangerous (electrics)?

4

I need to charge my camera battery, but I have no idea where the cable is. It uses one of those funky-shaped cords, and I’d rather not buy one just for it. I have a charger that I bought for charging my phone battery which always worked well for that purpose.

This battery has a third terminal type that isn’t on the charger (T) so I ignored it and just put the pins on the + and -. It was also too small, so I jammed some old bread in there.

Safe? Not safe? Should I go home and unplug it?

they say bread is life
