Topcat Battery Polarity - Les Wright - 05-30-2012

Looking at the "business" side of a Topcat battery pack, there are, of course, two terminals, eccentrically placed--one more or less central, the other nearer to an end.

Which is positive and which is negative?

Many thanks in advance.

Thanks! I am delighted to report that I figured this out otherwise and was able to use the info to zap back to some life 2 out of 3 beyond-dead NiCd Topcat packs. Very happy :)
