VEX IQ Battery Life Best Practices

Diagram of the Robot Battery being placed into the Charger. The Charger's LED light is labeled and noted to glow red or green once the Battery is connected to it.

Charge the IQ Brain battery whenever time allows.

Have the Brain Battery charge whenever it is not being used.
Keep all backup batteries fully charged and ready before storing them so that they can be used as soon as they are needed.

Diagram shows the two steps to remove the Robot Battery from the Brain. The first step has an arrow pointing at the Battery's latch to indicate that it must be pressed down. The second step shows the Battery sliding out from the Brain.

Disconnect the IQ Brain Battery whenever not in use.

Squeeze the latch at the end of the Robot Battery and push it out of the Brain slightly if not in use but charging is unnecessary.
