It says it "works on 9V DC 2.5 amp service". Is that a rechargeable battery sytem?

Mauricio is correct, it just means that it uses a rather standard 9V 2.5A DC adapter. For example, a Sega Genesis uses a 9V 1.2A DC adapter. These units usually use a large "brick" that plugs into an outlet, with a thin power cord; the "brick" is a DC converter, external to save space in the device itself.

No it comes with an AC to DC adpater/transformer that runs on 120v house current. No Battery.
582781
No, it has no battery system. I don't what that means. It comes with one power cord that plugs into a 110 outlet.

No. It runs on electric. It has a cord that plugs into the back and the other end plugs into an outlet inside my house. I have 3 of these. 1 in each of my full size bathrooms and 1 in my dinning room. They all work very well. They collect a good amount of water. I run them 24/7 and I'm very happy with them. The 2 bathrooms have no exhaust fans. They've did very well in cutting out the mold problem in the bathrooms.

Does not operate on 9vdc. Unit comes with 4ea AA alkaline batteries to operate the unit on 6vdc.

I do not have a 9V battery in mine and I unplugged it for five minutes just to test this. It did not seem to lose its tare weight or configuration information.

I know it's behind a screw in cover. I think it's a 9v, but I can't remember for sure. Battery life is ok.

its not a battery. its a capacitor (large value one). it takes a while to charge up (assume something like an hour or so, not a few minutes) and only holds power for short periods of time, such as a brownout or power failure. its NOT a battery, it cannot be replaced and would be dangerous to replace it.also note this circuit is not meant for 5v use. those using it on arduino should power the top lead (vcc) from 3.3v and not 5v! the i2c inputs are 5v tolerant.

Yeah, it does have a rechargeable battery for the cycle, the 9 volt is for the controller. Id advise opening it and charging the battery, I think it requires a 6-8 hour first charge

I was pretty sure it took a 9v, I just opened mine to confirm. 9 volt. Take care...

I'm not exactly sure what you are asking, but I own this speaker and on the bottom it says "Rechargeable Battery: DC==3.7V 1800mAh. I don't know if that helps, but I can tell you that the sound is very good and the battery charges quickly and lasts for a decent amount of time.

The back says DC 5V - where you plug it in. there is additional print on the underneath side that is so small I cannot read it. Sorry

Prior to answering, I carefully reread the instructions. No where is this question answered or addressed. I simply don't know. Technical info from instructions:" Power requirements: DC Adapter: 9vcd, 500 mA. Sorry!

I had the same problem. So, I tested the battery with a multi meter and it tested at 4 volts dc. That was the condition it arrived to me in. I tossed it in the trash and bought an equivalent from RADIO SHACK. It tested at 12.3 dc volts. I hope this helps.

No it requires 9v battery. You can buy the rechargeable type 9v battery and use it

I have connected it straight to a 9v battery and it works fine. It's not as bright as hard wired to a 12v system, but it does work.

Just wanted you to know that the wiring on this thing is backward, at least as far as the DC part is concerned. I don't use the AC part. In other words, it only works when you hook your DC input (battery) to the output side, and your output to the side marked "battery." The printed instructions that came with this item is wrong. If you hook it up according to the manual, it will not work.

Yes, as a matter of that that's precisely what I bought it for. If I run the battery all the way down I simply boost it for a very short while then switch to the 10 amp mode. The 2 amp mode works very well as a maintenance.

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

No where! The battery compartment of the unit is made for four AA cells only. Four AA cells connected in series, will give 1.5x4=6 Volts. Perhaps there is error in the sticker on the back side of ths gadget where it is written that the DC outlet should be connected to 200 mA 9 V (core negative) DC supply!! I have owned this dictionary for last 12 years and have gifted to many children and had not noticed this error. Thanks for pointing it out. BTW most of the DC supplies are core positive unlike the recommendation here, so if at all you wish to use a DC supply please buy the original unit manufactured / recommended by Language Master only to safeguard your dictionary.
