Hi, 4 batteries at 1.5 volts each is 6 volts assuming they are connected in series. They probably are. You want to be sure the DC power supply you connect is correctly polarized. That is, that the positive line is in the same orientation as the battery positive line, the + sign on the battery tip end. Most equipment won't operate the wrong way around and the battery arrangement is such that it is difficult to do anyway but some will be damaged if the polarity is reversed.

I want to rig an electrical transformer to replace those expensive batteries. Anyone know the proper DC current level I should be looking for?
