battery time is very short.
Note that:
• When the voltage in AGM or Gel batteries drops to 21.75 volts, the A1 Control Board switches off the
scrub motor, solution system and detergent pump, and raises the scrub deck. The vacuum motor can
still remain on.
• When the voltage in AGM or Gel batteries drops to 21.6 volts, the A1 Control Board switches off the
vacuum motor.
• When the voltage in Wet batteries drops to 20.55 volts, the A1 Control Board switches off the scrub
motor, solution system and detergent pump, and raises the scrub deck. The vacuum motor can still
remain on.
