@jumbo and @Dan. I dug into my replacement battery that didn\u2019t work in more detail. The voltage at the pancake connect (to the Mac) is 2.2v but at the raw battery leads 11.5v. The central battery board (BMS?) had two sets of very very fragile glued copper dot connections. I suspect that either these connections or one of the BMS chips is not working. Again, haven\u2019t gone into that much detail as I want my MB Pro back up. I\u2019ve ordered one from Amazon to see if it differs and works.<\/p>","url":"\/Guide\/MacBook+Pro+15-Inch+Touch+Bar+Late+2016+Battery+Replacement\/112876#comment-654008","date":1591969659,"date_html":"<time title=\"Fri, 12 Jun 2020 06:47:39 -0700\" datetime=\"2020-06-12T06:47:39-07:00\">Jun 12, 2020<\/time>"},{"title":"MacBook Pro 15\" Touch Bar Late 2016 Battery Replacement","text":"<p>Yep, same here except my MB Pro 2016 from Dec 2016 was out of warranty for about 7 months.
