Alkaline and Ag O button cells

  1. Nov 9, 2007 #1
    I read in maplin.co.uk that SR-41 button cells are superior to LR-41s.
    In what ways and by how much?

    Thanks

    SR are silver oxide, they have more energy/volume than LR alkaline and have a flat discharge curve. They also have a long shelf life if not exposed to air.

    Thanks. They should be suitable for my laser pointer.
