Charging and Maintaining Scout Batteries

This post is also available in: Français Deutsch


Scout and the Power Pack use Sealed Lead Acid batteries for power. Follow these recommendations to extend the life of your batteries and prevent damage.

Charging Best Practices

  • Allow Scout to cool down after recording in hot temperatures (above 30°C/86°F). Charging already-hot batteries will reduce their lifespan
  • Charge Scout as soon as possible after a deployment
  • Dismount Scout from its deployed position to charge (batteries should not be charged when upside down)
  • Keep the VCU door open while charging
  • It is safe to leave Scout connected to the charger for 12-24 hours after the charger LED turns Green to extend and maintain battery life and capacity – do not leave it connected for > 24 hours after the charger LED turns Green
  • Fully charge Scout every 30 days if it is not in use to maintain a safe battery level
  • Run the capacity test in advance of each count season, or a minimum of two times per year

Charging Behavior

  • The charger operates in three modes, Constant Current, Constant Voltage and Trickle Charge
  • In Constant Current mode, the charger will rapidly recharge the batteries to about 80% full
  • In Constant Voltage mode, the charger slowly charges the batteries to nearly full charge
  • In Trickle Charge mode, the charger tops up the batteries to full charge
  • The charger LED will turn Green in Trickle Charge mode*
  • The charger and Scout will become warm while charging; this is expected behavior**

*When the charger LED first turns Green, the batteries are not charged to their full capacity.  Leave the charger plugged in for another 12-24 hours to complete Trickle Charge mode and allow the batteries to equalise

**If the charger or Scout Control Unit are hot to the touch (you cannot leave your hand on them for more than 1 second) disconnect from power immediately

Charger Warnings

Under certain conditions, Scout will display a Charge Temperature or Long Charge warning. If this occurs, first run a capacity test, then download logs and send them to Customer Support for analysis.

Additional Information

When troubleshooting battery issues, you may be asked to measure Scout’s battery capacity using a multimeter.

If your batteries require replacing, please see the Battery Specifications article for purchase recommendations. See Replace Scout main batteries for steps to replace the batteries.
