TNA engines have a rating for 1.5V AA batteries so just any 1.5 V AA batteries should work.
Also TNA engines, at Least from what I've observed on mine, don't feature any fuses , they do feature resistors and those transformer any excess energy into heat. Even if one is damaged you can just remove it not necessarily replace as it's not entirely essential.
