Grumpy_Mike:
What about them. Link to one please.
However, it sounds like a very big battery considering the OP was using a coin cell to begin with.
23A(or AE) is the name/part number not the Amps available, but this is low, just thought it might be better than buttons. Size is about 38mm x 10mm diameter(1/2 AAA) i'll post link if i find one . . . . .
