What is BS EN 61951-2 – Secondary cells and batteries about?
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.
Who is BS EN 61951-2 – Secondary cells and batteries for?
BS EN 61951-2 on secondary sealed cells and batteries applies to:
- Manufacturer of secondary cells
- Electrical engineer
Why should you use BS EN 61951-2 – Secondary cells and batteries?
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.
What’s changed since the last update?
BS EN 61951-2:2017 supersedes BS EN 61951‑2:2011, which is withdrawn. It includes:
- Addition of battery type and addition of ‘F’ (high recovery type) designation for cells and batteries
- Addition of ‘I’ (low self-discharge type) designation for cells
- Revision of Figure 3 (6.1.3.1)
- Addition of “optional pip” note to the positive contact
- Changed leader line position from pip to flats of positive contact (B and G).
