Apple macbook Pro Retina A1398 Battery not charging

What is J5250? Can it have something to do with the problem? It's look like this (see picture).

As always, PPBUS_G3H should be measured with the battery disconnected. Charging circuit troubleshooting should be done with battery disconnected first. When the battery is disconnected, this machine should still turn on with a genuine Magsafe2 85W AC adapter, but it probably won't boot fully into macOS.
Battery not being recognized is a good indication that something is wrong either with the battery itself, the SMBUS circuit or the SMC.

I just noticed that it's seem to be that R7102 is missing ( attached pic of the board and of the file). Does this make any sense? Does it have something to do with my problem? on the schematic its says "NO STUFF". what does it means?
