Neato D3 Dead on Arrival

Neato D3 fresh out the box shows no signs of life. Left in the charger for about 4 hours now and nothing. Battery is not warm like I'd expect from a charging battery.

Is this common for this model? If so what are some steps to attempt to bring it back to life without going the route of a return/exchange.

Thank you

I don't have a D3, but when I received my Botvac, the battery was either partially disconnected, or the terminals were covered with a tab that needed to be removed. Did you have to do something similar? If not, maybe the battery cannot charge due to this issue.

Tested the battery with a volt meter and am getting absolutely nothing out of it. Something is definitely wrong with the battery.

If that D3 is using a Lithium pack, it may be in sleep mode and will require 12 volts dc applied to the power leads (Red & Black) to wake up the pack.

I thought the sleep mode applied only to the lithium replacements for NiMh systems, where the adapter electronics has a sleep mode for less drain in storage. There is no adapter to shut off in lithium battery systems. Sounds to me like the battery is defective. These batteries can have an under-and - over voltage protection circuit to prevent damaging over discharge etc., and if the battery is excessively discharged the protection circuit can cut it off. So maybe applying a charging voltage could get it back up, but what exactly is in those lithium packs has not been reported, and requires opening them up. A polyfuse is also likely inside the pack which can shut off if the battery is short circuited. A defect in that component could disconnect the battery. There may also be thermal fuses.
It is important not to over charge a lithium battery as well, why there are protection circuits. There is a fire hazard with these batteries compared to NiMh requiring more protection in the electronics.

If a new robot is delivered with any defects it is best if possible to return it to the store under whatever refund policy is in effect. I suppose this can be difficult in certain regions not heavily served by retailers. Still Neato Robotics should cover it under warranty.
