Bad connection to ascher wheel

Hi, are having a problem with Ascher B16M-SC Button Plate. Connection is now 58% and when it goes below 30% it start lagging gears etc. Any ideas how to get connection higher?


Maybe new Batterie.
How high are the Power?
All over 3V should be okay.

Hi, this is with new battery. So voltage is 3.5 volts
