Installing Batteries
in the EV3 Brick
The EV3 Brick requires six AA/LR6 batteries. Alkaline or rechargeable
Lithium Ion AA batteries are recommended.
To install the AA batteries, remove the battery cover on the back of
the EV3 Brick by pressing the two plastic tabs on the side. After you
have inserted the six AA batteries, attach the battery cover again.
Some important information about batteries:
+ Never use different kinds of batteries together
(including mixing old and new).
+ Remove batteries from the EV3 Brick when not in use.
+ Never use damaged batteries.
+ Use the correct battery charger under the supervision of
an adult.
+ Never attempt to recharge batteries that are not rechargeable.
Note: If your batteries are weak, the Brick Status Light may stay red
after you press the Start button, while the Display continues to say
“Starting.”
Power-Saving Practices

Remember to keep each set of batteries in its own storage
container so they can be used together.
+ Reduce the volume.
+ Adjust the Sleep Setting.
