Are these mechanically operated or do they require some kind of battery?

They do not require a battery. I haven't figured out how to program mine yet, but that may be more of a reflection of my skills...

It is a non-electric, mechanical push-button operation. No Batteries or electrical connections. It is the best one that I have seen because it has a hard rubber weather cover that also hides its function as well so is less obvious.

Mechanical. Simple. press buttons in right sequence. Buttons kind of hard to push in though I think ?

They can be operated manually or electric. The electric switch remotes have a habit of burning up, so don't hold them down more than a second or two. Otherwise they work fine.

They take rechargeable AA. Not that it matters. I replaced them thinking cheap factory batteries might be the issue. Nope. The units in my opinion are just junk, plain and simple.

Amy,They don't take batteries. They require a standard household power connection, normally 115v in the US.

Yes, through the manufacturer but they haven't carried them for quite awhile. We are still using batteries on ours for just that reason.

They are electric, so you need an outlet, or an external power source such as a generator.

No they do not... You have to supply your own batteries... This one is actually the best for your money....just buy batteries..

These are wired. No batteries. They replace the buttons you now have on a wall for opening the doors individually. They stay lighted for opening or closing in the dark.

No they are AAAA. Kinda expensive but last a long time. I am a mechanic and use every working day and the batteries prob last 6-8 months.

Most likely a small flat round battery. They come with batteries and they last long.

I think they are watch batteries, but they come pre-installed with the plastic pull tab, ready to use.

The ones I ordered are battery only with no way to plug it in from what I can tell.

Do they require AA batteries? If so: yes. These function exactly like batteries because they are Lol

They have internal batteries, not replaceable ones. But the units are ready to go (or get charged by the sun) when you get them.

Not sure, batteries are already included. I believe they are rechargeable batteries.

I opened them up out of curiosity and it appears that they do not use batteries. When you unscrew the 4 tiny screws in the back there is no battery area or batteries found under the battery door.

They are battery powered but the units are sealed. It should be good for about 10 years. I use them on all of my gas powered tools.
