The dummy battery allows you to fine tune the flow rate of the VP II pump when using AA batteries.
For example, you may discover that 8 AA batteries produce too much water flow and 6 AA batteries produce too little flow. Using one dummy battery in an 8 cell holder would be the equivalent to using a 7 cell battery holder. Using two dummy batteries in a 8 cell holder would be the equivalent to using a 6A-61 (6 cell holder).
