Ok folks, i think I screwed up, my Phantom 3 landed on the apartment roof upside down, it was in the 90's so I know the roof was well over 100. The unit was up there for several hours. Now after getting it down the battery won't charge.

Last week I plugged in a battery to charge and it did nothing.  Try this, plug the battery in to the charger then press the battery power button.  It worked for me.

Hello user423478b7d3, does the battery have any protection blinking during the charge?

It's common that crashing kills the battery, just get a new one.
