VEX IQ (1st gen) Battery Life Best Practices – VEX Library

Diagram of the IQ (1st gen) 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 robot batteries whenever time allows.

Have the Robot 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.

Disconnect the Robot Battery from the VEX IQ Robot Brain when not in use

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.

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.
