k i have a fuji fine pix s5600 and i just went to the store to buy some batteries for my camera and i saw some random no name batteries. in my hand book it says i can use alkaline or ni-mh batteries so i bought these no name alkaline batteries now i wonder if i can use those batteries or do they have to be name brand cause it says they certain batteries can leak or over heat so i am confused can i use these batteries i bought ?? or should i return them and buy brand ones just to be safe???????
