Battery Storage And Charging - iRobot DIRT DOG - MANUAL 2 Owner's Manual

Battery Storage and Charging

iRobot Dirt Dog is powered by a Nickel Metal Hydride (NiMH)
rechargeable battery. iRobot Dirt Dog's battery can last
for hundreds of cleaning cycles before a replacement is
necessary.
Battery Life
To extend the battery life, we recommend storing iRobot Dirt Dog's battery
in the robot with the power supply plugged in, or with iRobot Dirt Dog on the
Home Base (optional accessory). If stored correctly, iRobot Dirt Dog's battery
will take about 6 hours to recharge. If iRobot Dirt Dog is left off of its charger
for extended periods of time, its battery life and cleaning time will be reduced.
Cleaning Time
You should fully charge iRobot Dirt Dog's battery before each cleaning cycle.
When fully charged, iRobot Dirt Dog can clean up to 60 minutes. Cleaning time
is dependent on battery health, floor surface and room size, and may vary over
time.
16 Hour Refresh Charge
When charging for the first time, or if iRobot Dirt Dog has been left off the
charger for a long time, iRobot Dirt Dog will initiate a special 16-hour charge
cycle. This extended charge refreshes iRobot Dirt Dog's battery and extends
the life of the battery.
TIP: For best performance, always store iRobot Dirt Dog's battery in iRobot Dirt
Dog with iRobot Dirt Dog plugged in or on the Home Base (optional accessory).
Charge iRobot Dirt Dog's battery overnight for the first charge.
Charging iRobot Dirt Dog
Charge iRobot Dirt Dog by plugging the power supply directly into iRobot Dirt
Dog's battery charger socket.
