content: Just find yourself a lead that has a DC jack on it that fits that socket,look's like 2.1 or 2.5 mm pitch, cut one off a plug pack if you have to,observe the polarity, centre positive and hook it up to a battery or12 volt power supply.Muttley

content: $20 for a set of 2 batteries? Which gold plated, nude virgin, grey bearded wise old man tested brand of battery are you using.Either you buy batteries or you buy an appropriate power pack.If it is dead then don't throw it out. Salvage parts from it and build something that works.

content: 2 for $2.00 x 10/2 =$10.00 for 10 batteries I would not take the gamble.

content: I have a suspicion you don't have DC jacks laying around, but I'm sure you have a drawer with assorted lengths of wire.So instead of fiddling with the small connector just connect the car battery to the contacts in the battery compartment.
