This Exell A32PX 6-volt alkaline battery is a mercury-free replacement for the once popular mercuric oxide PX32 or E164 battery that was commonly used in cameras such as Yashicas (Electro 35GL, Electro GSN, Electro GTN, Electro AX, MG-1). Mercury cells, such as the PX32 are now banned because of toxicity and environmental fears. The A32PXA or PX32A cells produce 6.0 volts, which is higher than the 5.6V produced by the original mercury cell. Most devices accommodate the small increase in voltage and function perfectly. This battery has a height of 1.77 inches, diameter of 0.67 inches and features flat contact terminals. Exell Battery brand not only provide consumers with high efficiency and long-lasting performance, but they also function as replacement batteries for an array of common and unique applications. Ranging from vintage camera equipment to sophisticated testing equipment, they can meet the needs of all consumers. Exell Battery is one of the few product lines proudly assembled in the USA.
