Of course there were words over it, they were not happy the info was leaked. But that is not the topic here. I just wanted to clarify what had happened. You can contact me privately if you have any other questions. Thanks.
I use DeoxIT Gold on all my electrical connections other it be my UAV's, RC crawlers, my DSLR, etc. Well worth the few bucks for the tube as a little goes a long ways. I haven't owned my P3 for long and I have had zero issues so far. I have however flown my P2 for two years, also with no problems and I have used partially charged batteries.
I don't understand your theory on the battery terminals. If you find a loose battery terminal on a car that is abnormal, it should be tight. A properly seated P3 battery is normal and requires no repair. And what do you mean by "pull the two parts together"? Are you referring to the battery main power contacts that the male spade connector on the bird side slide into? Also, the two lower pins detect the batteries data. The battery contacts were redesigned on the P2 as they had problems with them losing contact from the lower two pins and dropping from the sky. Sometimes people don't have their battery fully locked in and it shifts enough to break connection and it falls. There are many reasons this could happen so I feel it is premature to say that a partially charged battery will increase your risk of complete power failure.
Here are the new & old style contacts -
