BATTERY: AG13 1.55V Alkaline

* Common low capacity primary button cell versions are typically called Silver Oxide batteries * Higher capacity versions available as secondary cells are more often referred to as Silver Zinc batteries * They have an open circuit voltage of 1.6 Volts. Two types of Silver Oxide batteries are available, one type with a sodium hydroxide (NaOH) electrolyte and the other with a potassium hydroxide (KOH) electrolyte * * Because of the high cost of sliver they are available in either very small sizes as button cells where the amount of silver used is small and not a significant contributor to the overall product costs or they are available in very large sizes for critical applications where the superior performance characteristics of the silver oxide chemistry outweigh any cost considerations *
