Just thought I would post this. A couple weeks ago I bought some alligator clips at harbor freight and have used a bunch of them on my chargers. http://www.harborfreight.com/28-piece-electrical-clip-set-67589.html I got mine on sale for $2.99 The bigger ones are actually big enough to hook onto car batteries.
thats a bargain , I paid $2 for just 2 small clips at jaycar "aus" a few days back , yeah only 2 bloody rouges !!
Nice find if you're in the US. I have a bag of 980 or so of gator clips that I bought in bulk a few years ago, I doubt that I'll ever run out of 'em in my lifetime.
