General Battery Maintenance Tips
•
Keep the battery charging at all times unless in use.
•
If Roomba is not going to be used for an extended period of time, charge battery first and
then take battery out of Roomba and store separately in a cool place away from sourced of
heat or direct sunlight. If it is not charged first it will deep discharge while in storage.
•
Occasionally reset the charging system in the Roomba (remove battery and hold down the
“power” button for at least 5 seconds and install battery), charge and run a “max” cycle
without the Home Base present.
Battery Troubleshooting
•
Batteries will deeply discharge when left in the Roomba unplugged. Roomba sleep current
(when not running and left unplugged) is about 7 mA which slowly drains the battery.
•
Batteries also naturally degrade over years. They should never be stored in a hot
environment.
•
Roomba can inaccurately calculate the battery charge capacity and not fully charge the
battery. Charging systems can be reset by taking the battery out, pressing the Roomba
power button for at least five seconds and reinserting the battery.
•
Verify that the Battery tested was charged in a Roomba. This is because a Rapid Charger
does not have the sophisticated software of a Roomba which dictates a proper charging
cycle based on the battery voltage.
•
The Battery latch may not be engaging well in the Roomba. Latches have been improved
and can be distinguished below.
