The answer
What to know.
The EON™ 100/120d charges with an IP54 conductive charger. Give the battery a full charge before using the robot for the first time. After charging, put the charging port cover back in place to keep the charging area dry.
Charging time
A low battery takes about 4.5 hours to reach a full charge.
Where to charge
Always charge in the shade, away from direct sunlight. The recommended temperature range is 41°F–95°F. Exposing either the charger or the robot to temperatures outside this range can shorten battery life and make charging faults more likely.
Battery indicator
During charging, the battery indicator on the robot's interface blinks green and progresses through the charge levels. A solid green light means the battery is fully charged.
