I recently purchased a Neato D7 and when it arrived, the device did not have a charge at all and will not charge the battery when placed on the charger. I've tried two different batteries at this point. The device will turn on and connect to WiFi when placed on the charger. The output from a diagnostic test is below:
____ Discrete: ____=
____ Analog: ____=
____ Buttons: ____=
____ Charger: ____=
It is quite interesting that the battery voltage reads 0 mV and am not really sure where to go from here. I have done all of the preliminary troubleshooting and still have not come to a solution. Also I have checked for any errors and none are present. Any help would be greatly appreciated!

Please post a getversion log also. You can delete serial numbers from that log if you dont want to share them.
Remove battery beneath the lid (two philips screws, it doesnt void warranty so its safe) and check the battery metal connectors. You can tight them with small flathead screw drivers. Then reinstall battery and test.
You could also check battery voltage directly from the connector, with multimeter.
Edit: Oh sorry, i didnt saw you already tried to different batteries.
You could try to setfuelgauge 50 to see if it has any help, i doubt, because it doesnt see any battery voltage. It also cant see battery temperature, even though log says thermistor is present, so is suspect there is a problem in the battery circuit on motherboard.

The results from getversion are above. I would try the setfuelgauge command, however I cannot enter test mode without some charge on the battery. Side note, I did the readings with the battery inserted in the previous output and did them again without the battery inserted and the results were exactly the same. It like the device is not detecting the battery at all. Does anyone know how to test the battery externally to see if it is a problem with it? I tried a multimeter on the red and black wires in the battery wire loom, but I didn't read any voltage there...

All Getversion logs SmartBatt details are empty, it just doesnt recognize battery at all. I suspect that either the robots motherboard battery connector is broken/bad soldering, or the Maxim fuel gauge chip is dead or it has a bad soldering. If its under warranty, you should return it. If it isnt, then we can move onwards to fix this thing.
Edit: You didnt get any voltage readings directly from the battery leads? Did you tested both batteries? Then the problem is on the battery itself.

Thanks for the reply. No there is not an active warranty in place and yes, I tried to measure the voltage from the battery harness and could not read any voltage from either battery. The weird thing is, I removed the heat shrink from one of the batteries and tested the individual cells and got 2.8 V per cell and the entire pack was reading about 8.5 V, but nothing could be read from the harness with the multimeter.

There is obviously an open circuit somewhere within the battery wiring harness.

Cell voltages are seriously below their design limits. I think the battery protection circuit cuts of outputs from the battery and thats why you cant detect voltage from the leads. You should try to charge the cells with RC lithium battery charger and then see if the battery outputs are active.

Thank you all for the help this far. Does anyone know what these batteries should read if they are brand new. I had a few more sent to me and the one that came yesterday didn't seen to read any voltage from the harness either. Is there a way to charge the pack enough without being in the vacuum that the protection circuit will close the circuit again?

I have tested 5 different batteries and none of them read any voltage from the harness (red & black). Is this supposed to read voltage? I am confused as to why all of these new batteries would be defective or extremely discharged... The most recent one tested was purchased from Amazon
with one day shipping. Could anyone elaborate on this?

To anyone who might be having the same issue, replacing the battery with one bought from amazon
did the trick for my vacuum. The previous batteries I had came from the person who I bought the D7 from originally and apparently they were either all defective or all extremely discharged. I tested all 5 batteries with a multimeter and found that none of them would return a voltage by testing from the harness, but the battery from Amazon
charged once place in the D7, which none of the other would. Thanks to everyone who helped out.
