Help with changing battery in Small and Large Chip Resetters

Need specs on small button batteries and installing. Using the Acc-Resetter-SF and -LF. Trying same 1.55V 192 battery, assuming that’s the right one, and not sure if (+) is up (away from board) or down (toward board).

  • is up. The model # of the battery should be actually on the batteries in there. There are three. Usually just taking them out and shuffling their positions fixes this.


I removed the batteries long ago… they drained. So no model to read from. Can you confirm 1.5V (the size I have is perfect); just not sure of voltage. Thx.
