REPAIR & TROUBLESHOOTING - Mercury Battery Adapters
Comprehensive technical guide addressing the replacement of banned mercury batteries (PX13, PX27, PX625, PX32, PX400, PX640, PX675) formerly used in vintage cameras and exposure meters. The document evaluates available battery technologies (zinc-air, alkaline, silver-oxide, rechargeable, and lithium), explaining why most are unsuitable for direct substitution without adapters or circuit modifications. Key sections include comparative discharge characteristic charts for various battery types, six replacement options ranging from professional servicing to homemade solutions, detailed selection criteria for Schottky diodes based on device current draw, temperature effects on diode performance, and specialized guidance for PX27 battery replacement. Features output voltage comparison graphs, step-by-step construction procedures for both discrete component and S.M.D. adapters, sourcing information for commercial alternatives, and an extensive compatibility list of cameras and light meters. Essential reference material for vintage photographic equipment restoration and repair specialists.
