The system runs on both DC (battery) and AC (see the power adapter) in the middle.

This unit has a power supply -- 110 volt. I do not believe that a battery is utilized.

NO - The manual says to remove the batteries if it is not going to be used for a while.

No. It does not require batteries. It uses the 24 volt power from the HVAC unit.

My unit came without batteries, so I had to use batteries, unless I purchased a power cord. The unit requires six (6) AA batteries, which seem to last quite a long time, maybe around a year with normal usage.

Yes, but I use the battery alone without the plug in power. My shop is off grid so it is nice that I don't need to plug it in.

Sorry I can't answer that question. I always have it plugged in and do not rely on batteries.

This unit does not require batteries, but it does require mini-USB power for the built-in speaker (it also charges the GPS).

You could use a Lith battery. When you get the unit test it immediately. The unit I received had a defective manual function.

Yes, you can run with only the supplied AC adaptor. Not necessary to have batteries.

Yes, but do not mix batteries, only use this style if not it will ruin the unit

It doesn't need batteries. Mine too inexplicably stopped working after a short while. I had to return it.

Does not need batteries. Robust and reliable. I use it in conjunction with a laser unit to read surface and core temps.

No, it does not require batteries. Just plug it in. It has a nice storage area for the cord underneath also.

I'm not 100% certain but I'm fairly sure you don't need batteries. it is a landline that connects to the wall.

Correct. The unit does not come with batteries out of the box, but you may use regular or rechargeable batteries.
