1. Is this required one 9V battery?

As I remember, it does. We returned ours as both the original tester and subsequent replacement we were sent came with defective remote units.

Yes , you will either need a battery or a 9V adapter. You will also need to have something in the ins and outs for the led to come on. Be careful though, my first one was dead on arrival. Good luck !

No, it only comes with one battery but it's rechargeable (and comes with a charger).

No; find no battery well in the unit; uses step-down transformer for 120V to 9VDC 2.5A minimum

The Weighmax 35 lbs Postal scale I ordered came with a 9V battery. That is what it uses, one 9V.

I was pretty sure it took a 9v, I just opened mine to confirm. 9 volt. Take care...

No, it does not need a battery. I did not put a battery in mine and it worked fine.

i have no idea if there is a 9volt battery in the unit. the pkg and instructions does not mention anything about a battery comming in the unit. you have to unscrew the unit very carefully or else you will easily strip and never get them off. find a jewlers screwdriver set. also, find a free image or photo site that you can post an image of the problem.

No it requires 9v battery. You can buy the rechargeable type 9v battery and use it

Mine did not need those batteries. The older version I had needed a 9volt battery as the backup but the new version came with a large "watch" type battery. I did not even look in the manual about anything else so don't think it needs them???

No, it uses two AAA batteries and this is one of the main reasons I bought it. I use rechargeable AA and AAA cells and avoid 9v if possible.

It is for one but the price was less than a local battery company. I had to return the first one they sent b/c it wasn't the one ordered but they immediately sent the right one and it works just fine.

No. Everything action this set does uses Lego pieces. The 9Volt battery you see on the box is actually made out of Lego & is there to make it look like it's giving power. But to answer your question it does not need batteries &#128522;

Hi Joan,Ours only came with one battery, however I'm sure you could order another if needed.

Not directly. The motors are 3 volt motors and if you provide higher voltages, the motors will be damaged over time. The kit comes with a battery holder for 2 AA batteries. If you absolutely need 9 Volts, you can either look for 9 volt replacement motors or use an inexpensive voltage converter. These guys http://www.pololu.com/ have a great selection and they may even have replacement motors.

no it's one battery but we have looked else where and not only are they a bit hard to find...the price is expensive. I bought two as back ups
