Final Update: Yes it was indeed centre negative. I spoke to some (more) knowledgeable local tech friends and they tell me it is highly unusual, but centre negative is somewhat standardised for use in charging batteries on board RC toys etc. I obtained a replacement pineapple board and am back in business. I'll revisit battery powering my pineapple a little ways down the track.

I am travelling at the moment and don't have my multimeter with me. But it I don't recall ever seeing a DC plug in Australia that is the other way around. I have checked all the plug packs i have with me at the moment and they are all centre positive.

Uhh..... :( I bought a 1300mAh Lead-Acid 12v battery with pre-made DC connector with alligator clips (to connect the battery) and when I connected it the magic smoke escaped the Pineapple. :( I know this battery would not last to long with the pineapple at load with clients attached, but I got a small battery just to test with. I told the guy at the electronics store the exact requirements for the pineapple (5-12v @ ~1amp) and he recommended a battery (see below). The pineapple will no longer power up on it's normal DC supply :((( Here is the battery: http://www.jaycar.com.au/products_uploaded/SB2480.pdf The clips i used to connect it: http://www.jaycar.com.au/productView.asp?ID=WC6014 What have I done wrong here?
