Batteries required for headsets (either AA or AAA-I don't remember) and 12-volt battery for transmitter can be found on amazon or any hardware store ($20) and would have to be replaced eventually. I would sooner recommend the ones I finally purchased on amazon- Unisar TV Listener J3 - the transmitter plugs into AC outlet; headset comes with rechargeable batteries

The one I have is a metal sword. The one that needs the batteries is a plastic sword the glows blue through the gray plastic.

3 'AA' batteries can replace the rechargeable battery. I keep 'AA's as back-up when I'm out and about with the units. They make Lithium 'AA's now that are supposedly the best for gear like this.

This radio requires 3 AA batteries which you must purchase. Additionally, it has a 6 volt dc socket for an after market transformer or power source ( check radio shack or Wal-Mart) next to the plug for a head phone. I usually get about 50 to 60 hours before changing batteries depending on brand.

Helmet strap is sold separately. I bought a head strap separately (not for helmets) and it came with a longer cord to connect to the battery pack.

they take a aaa rechargeable battery. There are 4 screws under the top section along the side. Remove all the screws and the top will come off and you can replace the batteries.

It comes with a 9v battery for each transmitter. The new headset fits much tighter than the old one, bad design.

It takes a CR2032 watch type battery. Can't tell you how long it lasts as I've not had to replace yet.

There is padding on the forehead strap. The helmet is about as comfortable as any other welding helmet. If you haven't used it in awhile leave it in the sunlight (outside sunlight is better than through the window) for awhile so the battery recharges. The battery will go dead if you haven't used it in a few months.

It uses three watch batteries. They are available at a battery store. Not available everywhere, too specialized.

It does not come with either and I don't use the behind the head accessory. The 2nd battery is a must however. Battery life is very good but when it gets weak, you'll need to replace it quickly.

Not sure what they're called, but it's a large round battery. They sell them in the watch department, they're pretty cheap.

It comes with batteries in it - they are small "hearing aid" type batteries.
