T6 same as others. don’t be surprised if the machine thread nut that is molded to inside doesn’t break off i just tighten them back with cover off and put some epoxy glue as i reattached cover

I did the procedure of removing battery and plugging in charger then reinstall battery. worked for me. the tiny screws are a pain. also panel that covers bottom with rubber pads has three machine threaded screws had two of three broken off. i epoxied then back to base.
