Red is positive, black is ground. That's pretty standard for DC electrical systems, not just cars. If there is an additional negative potential, it will generally be green.
Damn good thing to know. I too wondered about pos and neg. I reckon if it didn't work one way, pick yer ass up off the ground if need be and turn er around.
They sell little lithium-ion battery packs about the same size for emergency vehicle starting. The main difference is that they have leads with alligator clips.
So what part is positive and negative?
ReplyDeleteRed for negative (I think), and orient the battery in like manner to the video. :P I'm tempted to try it with a completely dead car out back.

ReplyDeleteHow can you tell positive and negative on the rechargeable?
