Can I use LR-43 batteries in LR-44 games, and vice versa?
A. LR-43 batteries will fit in most LR-44 game aside from the V's, and may work, in some games due to their size, they may not make good contact with the terminals. They most certainly will not last as long as an LR-44.
L R-44 batteries SHOULD NOT be placed into LR-43 based games, particularly the silver’s and gold’s, as they will most likely damage the game causing the terminals to be bent or the battery cover to break.
