Does it still work if you just don't use a battery? Can I just not use the backup?

This model requires you to have battery backup and is designed for your safety. CO poisoning is most likely to occur during power outages, and without a battery backup you would not have a functioning CO alarm.

no battery backup but you will not lose any phone numbers that you want blocked.

I bought one earlier this year. I don't know that answer. It chargers my Nextbook Premium 9. Don't know anything about using it without a battery.

You will not need a battery anymore. Just hook to your device and plug in. It's not a charger.

Yes, you can use without the battery. With the battery the recording time is not long , less than two hours .This product is very good , I'm very happy , buy it for very little $ 140 d and quality sound recording and video is spectacular .

As someone else replied, this has no battery backup. The description must not be clear on that. Others have asked the same question, and I had to replace when found that there was nowhere to put the 9v, which is local code.

I do not know because I have not used that feature on our phone yet. I know there are no batteries for back up.

It will function without external power. Using external means there is less drain on your (Laptop) power.

Yes, it will work fine. I'm using mine right now without the battery. My battery is bad (3 yrs. old) and the unit will lock up with the battery installed so I removed it.

It does not have a battery, you will need to unplug it before moving it from one location to another.

It doesn't need a battery....it has a charger. There will not be a dead battery.

Yes but it can Block the cell signal making it much less then it would be without the battery on. So if your signal is low to begin with it may not be a good option

It does not use any battery. It connects to your source and the power is derived from your source i think.

Glad this was addressed...was thinking about buying one but not if it doesn't have a battery backup.

No battery backup built in but it uses the battery from the the alarm system. It has retained my zwave configurations after being disconnected. Most of the alarm programming is retained on your alarm system. IP address and such is usually DHCP.
