88000 Power Functions AAA Battery Box is a TECHNIC Power Functions set released in 2011. The set comes with only one piece and was originally only released in Switzerland, Austria, and Germany, but is now available at the Shop@Home in other countries.
The battery box measures 8 studs long, 4 studs wide and 4 bricks high, exactly the same as 8878 Power Functions Rechargeable Battery Box. It holds 6 AAA batteries and can power 2 XL motors or 4 M motors at one time. The box is mostly dark grey with a light grey top. On top is a green on/off button with an LED indicator, an orange reversing switch and a connection point for power cables. This battery box is most often used in Trains sets.
The battery box will automatically turn off after 2 hours. However, the auto-shutoff can be disabled by pressing the power button for 3 seconds. The LED will blink, indicating that the battery box will stay on until turned off or the batteries drain fully.
