EV3 Brick

Installing Batteries

With LEGO

MINDSTORMS

Education EV3, you have the choice of

using normal AA batteries or the EV3 Rechargeable Battery pack

included in the LEGO MINDSTORMS Education EV3 Core Set.

If you experiment with both, you will ﬁnd that each option has

characteristics to consider when constructing your robots. For

instance, six AA batteries weigh more than the Rechargeable Battery,

and the EV3 Brick with the Rechargeable Battery installed is slightly

larger than the EV3 Brick with six AA batteries.

The EV3 Rechargeable Battery is a convenient and economical

alternative to using AA batteries. It can be recharged while inbuilt in

a model, saving you the trouble of disassembling and reassembling

a robot to replace batteries.

To install the Rechargeable Battery on the EV3 Brick, remove

the battery cover on the back of the EV3 Brick by pressing the two

plastic tabs on the side. If there are batteries in the EV3 Brick,

remove them. Insert the Rechargeable Battery in the slots that held

the battery cover in place and snap the battery in place. The battery

cover is not used.

If it is your ﬁrst use of the battery—or if the battery is completely

drained, let the battery and the EV3 Brick charge together for

minimum twenty minutes.

Using the enclosed power adaptor cord, connect the Rechargeable

Battery to a wall outlet. Make sure to keep the transformer cord and

battery where they will not be tripped over or get wet.

When you plug the uncharged battery into a wall socket, a red

indicator light will be lit. When charging is complete, the red light

will go out and the green light will be illuminated. The recharging

process will generally take three to four hours. If you use the EV3

Brick while the battery is charging, it will take longer. Before you start

to use the Rechargeable Battery for the ﬁrst time, it is recommended

that it is fully charged.
