BS EN 61951-2 is a European standard that discusses Nickel-metal hydride secondary sealed cells and batteries for portable applications for Secondary cells and batteries containing alkaline or other non-acid electrolytes.
BS EN 61951-2 specifies marking, designation, dimensions, tests and requirements for secondary sealed nickel-metal hydride small prismatic, cylindrical and button cells and batteries, suitable for use in any orientation, for portable applications.
BS EN 61951-2 on secondary sealed cells and batteries applies to:
A sealed cell is a cell that remains closed and does not release either gas or liquid when operated within the limits of charge and temperature specified by the manufacturer. A portable cell is designed mainly for use in an easily hand-carried battery. Nickel-metal hydride is a cell containing a nickel hydroxide compound for the positive electrode, a hydrogen-absorbing alloy for the negative electrode, and potassium hydroxide or other alkaline solution as an electrolyte.
As a user of BS EN 61951-2, you can ensure the quality of nickel-metal hydride batteries as the battery is carried by the guidance containing rated capacity, nominal voltage and date of manufacture which provides the safety cautions for the nickel-metal hydride for portable applications.
With obedience and compliance to BS EN 61951-2, you can efficiently provide the ecosystem for nickel-metal hydride for portable application through secondary sealed cells and batteries containing alkaline or other non-acid electrolytes. In this manner you can deliver high-quality products.
