Does my NAO have a battery problem?

As long as the battery is inside the NAO, it is delivering a small amount of electricity to the robot, even while shut down. If the NAO sits for a long time unused, the battery can become so depleted that it can no longer be charged.

If you suspect this is the case for your battery, here are some of the telltale signs:

• Your charger light turns green in just seconds when you plug in the NAO battery.
• Your “fully charged” NAO only runs for a few seconds, or shuts down before it finishes booting up.

• Your NAO turns off instantly if you unplug the charger.
