Designed and constructed in Australia the Neo Geo Battery Blaster is a drop in coin cell replacement for the MV1b and MV1c that requires no removal of other parts. The Battery Blaster blocks the original charging circuit so there is no need to remove surface mount components to install a 2032 coin cell battery. Just desolder the original rechargeable battery and install the battery blaster in the 3 original battery holes and you are good to go. Battery life is not affected while your high score and save states are stored for future gaming sessions.

Installation does require desoldering and soldering and I take no responsibility for damage resulting from these tasks.
