My control box came with a battery back-up, I have had this unit for 3 yrs and very little trouble with it, it is a inexpensive unit, you get what you pay for.

This system does not have a back up battery but you can always buy a UPS (uninterrupted power supply) battery back up for it. You will plug the back up battery into the outlet and the system into the back up battery outlet. I plug this system above my dropped ceiling in my business and all the wires were ran in the exterior door's molding. The exit button wires were ran through the wall and around the exterior door's molding and connected to the keypad. The UPS can be used on anything like computers, alarm systems or any kind of medical devices that need power to stay on even if there is a power outage.

No, mine came without the usm battery, i don't know of anyone that did get the battery, no big deal for me, i love the computer, super fast, quiet, runs cool, don't pass it by just because of no usm battery from amazon, u might be able to get it with the battery from another vendor, might cost more though

There is another set that comes with the pump and back up pump, if you are installing the whole thing. This one is just the back up pump and you need to purchase a battery to go with, my husband got our battery at the auto part store, should tell you the correct kind of battery in the instructions.

It comes with a battery, but they don't last very long. You can find them pretty cheap here.

You shouldn't have to have a backup battery. These batteries last a long time. And you only need one if you have the phone service

It comes with a battery. It's a duracell so you might be able to order from Duracel web-site? OR you could probably get one from Sears or Home Depot.

Yes, it comes with a power supply and also three mounting screws and detailed instructions for setting it up. It does not come with a 9 volt battery for backup.

I found it. You can buy at Ebay. The seller ID(name) is trusyou11730. You can buy extra battery too.

Yes the original Sony battery as well as an aftermarket backup battery. I preferred this bundle over others because the extra memory card was a high speed Sony card, not a cheaper version.

I did not receive an additional battery at no cost. But I believe there was an offer at on time where purchasing the system and a additional batt would discount the batt to zero cost. I did not get this rebate, but I would seek it if still available, as another owner stated, additional batts are a nice to have.

I missed that you asked about the battery also... yes it comes with a battery.

Hi,I have been following the thread as I also would like to have a backup in case of power outage to plug in my PC or reading lights, a coffee maker :)The battery mentioned seems to be hard to get, do you have an alternative?

My order came with a battery. The only thing I needed was a memory card. I tried to get a backup battery but my local battery shop that claims to be able to get any battery were stumped so I still only have the one battery that came with the camera.

All of those items has to be purchased except the back up battery. The GSMVLP and the 7847i are two separate items that are not included
