I want to make a battery tester. I am in the UK.
I'll use a fixed metal sheet which I will press the positive stud of a
cell on. (A meter probe will go to the other end.)
(1) I tried an aluminium sheet for the metal but it didn't make good
contact possibly on account of repeated re-tarnishing.
(2) I'm considering a metal strip like the contacts on a 1289 (3LR12)
battery: http://www.smallbattery.company.org.uk/sbc_3LR12.jpg
However I think the strips are and when I look at the electrical
conductivity of brass it seems quite poor compared to copper. If brass
is really a poor conductor then why is it used on a battery?
(3) What alternative material could I use? Perhaps a plated metal
sheet of some sort?
