Battery management is a key component of operating a successful robot.  The charger is vital to the battery management, and below are some suggestions:

  • Use the “Fast Charge” switch position for the 3000 mAh Ni-MH batteries.
  • In the fast charge position, recharging a dead battery will take about 105 minutes.
  • During the 6-week build cycle, use the batteries until they are discharged before recharging.  On competition day, keeping the batteries charged (without full discharge) shouldn’t hurt their performance since Ni-MH batteries are less affected by battery “memory.”

The AAA batteries are used for the Vex Joystick.  Below are some suggestions for using the AAA battery charger.

  • Install the batteries in the charger before applying power to the charger.
  • The recharge time will be over an hour for fully discharged batteries.
  • A red light indicates the battery is being charged.  The light will change to solid green when the charge is complete and the trickle charge starts.
  • A flashing red light indicates a bad battery.
  • If you press the blue button within 1 minute after applying power to the charger then the discharge cycle will start. A flashing green light indicates that the battery is being discharged. After the discharge cycle is complete for all batteries, the charge cycle will start automatically.
