I bought Phantom 4 with three batteries beginning of Febuary 2017.  Use each battery once.  Now none of them charge or reaction when button pushed.  What should I do?
Help!

Sorry to hear the battery issue, just to verify, your purchased them from DJI directly or a local authorized dealer?
How long you've charged them? The remote controller can be charged properly with the charger, right?

I bought on Ebay new.  The charger charges fine.  I let it charge overnight.

The batteries seems to be faulty, please contact the dealer to help you handle it firstly.
