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

It does not use any battery. It connects to your source and the power is derived from your source i think.

No, it does not use electricity. It's basically a storage bin/rice dispenser. It's well worth the price.

No batteries required. It is powered through the pins via whatever you dock it too, much like docking your phone/iPod.

It does not use batteries. You have to either plug it into an outlet or the car.

No battery required. It uses power source and you need to have a long power cord of your own.

No batteries, you just plug it into an outlet. Just make sure that where you plug it in, the cord can droop down a little bit before it goes back up into the outlet, just in case some moisture gets on the cord so it can't get to the plug and electrocute you (that's what it said in the instructions). The cord is pretty long so it shouldn't be too hard to do that.

You can use batteries but it does come with a cord. I would suggest the optional extension cord as well.

There are no batteries necessary. The unit is powered by a transformer that plugs into a standard wall socket.

It needs batteries for the laser. If you just want to use the level adjustments then that requires no power

I never installed batteries but as I recall it needs them or the AC power to operate.

It comes with a power supply for the wall outlet and yes it requires batteries only if you want to use it wirelessly.

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

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