can it work just on batteries

Yes, but check with your local code authority to be certain your application meets the code requirements.

well - it has a port for a plug in, so I went to Radio Shack and got what should have worked - and nope. So I would say no. It does run for a really long time on batteries though

Yes, it only runs on batteries and it is very easy to move around in the house.

It can run on just batteries. It actually last a lot longer that I anticipated. This is one of the best investments I have made in the caregiving of my elderly father. I know most people use it for babies but it definitely works well in any caregiving situation!

It only works by being plugged into an outlet. It is not made for batteries.

No. I tis designed to test off the shelf batteries. I personally have used it to test rechargables. It works on some but not on others. Have no idea why.

Yes -- it can work either from the battery or while AC is connected to charge the battery. There is a storage switch under the remote that you turn off if you're going to store the unit for a while.

No. Only the correct 12 Volt batteries will work. (This way they make you buy different batteries)

Yes, works with AC adaptor only. I don't even put batteries in unless I'm going to be using it where AC isn't available.

Yes. The only thing that does not work on batteries is getting a live feed at anytime. The doorbell works fine and the camera.

I have mainly used mine with the power cord and the batteries inside. I would think that it would work with the cord only.

Probably but only over a long period of time and it will only maintain a charge, not charge the batteries up from dead or low.

I didn't look to see if it ran with batteries. It would be impractical. Get a electrical cord long enough for whatever you plan to use it for.

Mine unit did not work at all... So I returned it next day ... I don't remember if both units work on batteries or not. Sorry

no you have to plug it into a power source. that's the only way it will work.

Yes it can. It comes with an AC Adapter. I usually keep mine plugged in. There are no batteries.

Not exactly. It will work only on 120V ac outlet. Optionally if you have an inverter which converts dc voltage to ac voltage that will do the trick.
