They do not. They are noise isolating, but not active noise canceling, if that's what you're wondering about.

No. They use a plug-in battery pack. You can get them on-line through Amazon as well as other battery specialty sites. They have a long life and are not expensive to replace.

Hi-No, these do not have batteries. They will not work with your TV.If your 3D glasses require batteries, they are "Active" glasses. These are "Passive" glasses. the two technologies are incompatible.Marty

No, they are simply rechargeable batteries (excellent batteries for the cost) and like any battery of this type they rely on the devise they power for protection. Hope this helps, Have a great day.

They do have batteries in them. I love them but your getting what you pay for. It's cheap they last about a month with regular use. Then I tossed it away and put on a new one. Ordering extra is cheaper than replacing batteries.

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

No, they only work with batteries but you can buy rechargeable batteries and the batteries charger and get the same results.

Yes. The only thing I've found tricky with these is getting the battery compartment open. Once I figured it out, it wasn't too bad. Don't forget to turn them off when you aren't using them -- the battery will run out! (I use them at work and accidentally left them on over the weekend. Luckily, I had a spare battery in my desk!)

If I recall correctly they take AA batteries. The battery life would depend on the batteries, I guess. We don't use them for very long at a time so I am sorry I cannot be of much help.

I don't recall seeing anything about a battery, I think they must be plugged in to use.

Yes, the ones I bought came with batteries. Replacement batteries are easy to find and install.

No, no batteries are required!But if you're using them for a really little kid, don't knock them around too much. They're a really good product just won't withstand a lot of abuse

No. Batteries only. Works very well, but you'll need to use good batteries with this. I used cheap dollar store brand batteries first, and they didn't last very long.

Yes, they are rechargeable batteries. I will say I wished they lasted longer. I think mine last about 1 hr when not hooked up directly to the outlet.

Yes they do! with a little activation strip, so you can be confident that the battery isn't used or worn out.

I have no suggestions. These did not work for me at all. I know of none that use a battery.

Mine doesn't use batteries at all. No moving or lighted parts. Strange that they'd even mention them. *shrug*
