LOL. It requires no battery. It's a beautiful, cylindrical piece of rosin. Highly polished.

It doesn't. I'm not sure why they put it but it doesn't come with a 'AAAA' battery ether.

This does not require a battery. this is rosin for violin, viola or cello. This listing for this item has some incorrect information and needs to be updated.

No it does not require batteries. It connects direct to your mixer via a 1-4inch jack.

I didn't know it did need batteries.I have it on the wall, plugged into the telephone line.It works just fine...no batteries that I know of.As another reviewer said, it is a wall phone. The "od fashioned kind".My grandkids didn't even know what it was, hanging on the wall. :)

It must be plugged in. But it does have a battery because there is a CAUTION: Risk of explosion if battery is replaced by an incorrect type.

Its either. I believe it is so you can DC out to another product. Or, apply another battery as stated below. The instructions do not discuss the issue.

Mine came with a battery. I did however order a battery at the same time because I was unsure. But it did come with one.

no batteries needed, it plugs into the USB port on your computer. You can buy a power supply for use elsewhere.

Im not sure where you saw that it requires a battery. Its just a case. With a magnetic to keep it closed. There's nothing electronic about the case itself.

Hi Beth, This device has no battery. You need to connect it to a power source. -Anthony

I'm not sure I understand your question. It is an electronic device so it needs a power source. The battery is built-in, and can be recharged through a USB port on a computer or laptop.

It does not come with a battery, you will need to buy one or use one from another tools you may have.

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

No, but it doesn't need one. Power consumption is exyremely low when it is on standby.

this product doesn't run on batteries. it plugs into the computer's usb port and gets its power from that source.

No, it does not need batteries. It is a manual clacking spring alarm that goes off when the door is opened.

It doesn't need a battery. I think what caused confusion is the need of cordless phones to have a battery to charge to be able to receive a signal. This is an "old fashioned" phone that is directly connected to the phone line. If the electricity goes out, it is not affected.
