Is there a low battery warning and can it be used with a 9V power adapter.?

Not sure about adapter . Would have to check on specifications also low battery warning havr to check online.

That is a dc rating for the power supply, not the battery. The battery is 10.8v 4400mah.

The spec sheet doesn't say that number outright. However, if you use a 5v useable voltage cutoff (which they do in the data sheet), the battery will go 310 Hours at 2ma (620mAh), and at 10ma it will go 60h (600mAh). So there ya go. However, if you're using a 9V, your circuit probably needs at least 7V to run, so keep that in mind while choosing capacity.

I found the specs for this on the back of my package. On the back it says: Charge both 8.4v and 9.6v NiMH 9V battery. It looks like it will work for a 9.6 volt if it is a NiMH battery.

Yes, I'm not sure but I had it running for about 3 hours off the charger and I had no notification saying that the battery was low

it can run from as low as 5v (at least 1amp but 1.5amp is better). 9v works fine. 12v is what is listed but since it works at 5v, 12v seems a bit too high to me (extra volts are burned off as heat; never a good idea). I suggest using a good strong 5v dc psu.

You might have already found out by now 2weeks later, but it does come with a 9V power supply. It does not run on batteries. I own one. Previous replies are incorrect...

It will allow you to forgo using the 9V battery. It plugs into the wall and the other end plugs into the device that would use a 9V battery.

You can use it both with batteries or pluged into a 9v power source. But there's no AC adapter included !!!

Sorry, but I do not use regular 9v batteries. I always use high capacity 9v rechargeable battery like (iPower Pro). And they last about 8+ hours and take about 45 mins to recharge.

I power mine with the USB connection. But I'm sure Amazon has a 9 volt adapter that will work. Just check specs to make sure you have a match.

I don't really know. But, I would say no, due to the fact that if functions with a 9V battery.

Boss makes an AC power adapter that is sold separately. You can also run it with a 9-volt battery.

That is a good point, but I rarely have a dead battery in my trailer (solar) and I do have a battery alarm when the voltage gets low. And I don't have to worry about changing a battery on the monitor when it goes bad. Good luck with your research.

These are good units. I have bought 4 sets and have served me well. They should work with a 9volt battery. Battery will only last about 8 hours max. I have not done it on these units but on all my others I have I do not see why it would not work. If you want I can try it and see. Let me know if you want me too. phh57@att.net

The adapter only allows the use of batteries that otherwise wouldn't fit, Neither the adapter nor the battery (or the equipment it powers for that matter) contains any low-voltage cutoff circuitry that I know of. You will know the battery is low on charge simply through its exhibition of degraded performance. Hope this helps.

no it has low battery warning, it will turn off prior to killing your battery
