Yes it runs with battery and the unit can be taken to Battery's plus and they will change it for you!!!!

yes there are 2 small round flat batteries. They come with the unit and are easy to replace. Be sure to TAPE the back.(battery cover) I have lost the back piece, it slips off.

It requires two Sony CR2025 batteries. I bought replacements from Fry's.com. For long trips it is a good idea to have a pair of extras.

The unit works only via a DC input - no normal facility for a battery. But if a battery is essential, a technician could certainly adapt a heavy duty battery and attach a chord which would power the unit. The unit is first rate, incidentally, and performs just as advertised.

I don't think there is any battery in there. You need to connect it to a socket.

You will need to purchase the battery it does not come with one. It runs about 90 minutes on a full battery charge. It also runs on ac. AC charges the battery and the unit can run for hours. I have not tried it for 12 hours. Over-all a nice compact and bright unit.

Doesn't need a battery, will run standalone on AC. On a side note we love ours, still going perfectly.

Yes you can power the system by battery. Just be sure to use fresh batteries when installing them. The unit will have a visual and audible warning when the batteries are getting low to warn you to replace them.

No batteries. Runs on house current. I bought two and sent them back the next day. Poor reception even with an outside antenna!!! I do not recommend you wasting your money.

No, it doesn't run on battery. It gets its power from your PC when you plug in the USB connection.

Yes, it will run on a battery. I have used it in a storage area without power. It uses a 9V battery.

No the vehicle does not need to be running. This unit can be wired to a charged 12V battery. The battery wired to the unit provides the power.

I am unsure if there is a battery back up, I will check. We run ours from an AC adapter.

twist/ turn the unit to open for mounting & wiring. There is no internal battery.

No, unless you can convert battery to AC. :) Still not sure how long that will lasts if you want to run it 24/7

No, but when plugged in to 110v AC it does not use the battery. If the AC converter is plugged in to the unit it will not run on batteries even if it is unplugged from the wall.

Correct. The unit does not come with batteries out of the box, but you may use regular or rechargeable batteries.

My unit was shipped without the battery. Did you make sure it has a battery?
