Fully charged battery needs power cord to wake from sleep

New battery in Mac Air 2015 11”. After going into nap mode, the Mac needs power to start up, but then I can immediately unplug and the battery is charged at the % where I left it. If it never naps, the battery works fine without the power cord.

mmm… This is not a new battery! It’s been sitting on a shelf since 2015?? Or is this your original battery??

Sadly, batteries wear out just sitting on a shelf or even inside of a system which is always plugged in to power.

So is the information here from the wrong battery or is SMC messed up. Let’s carefully disconnect the battery and with nothing plugged in press and hold the power button for a good 15 secs to fully discharge the logic board. Now carefully plug in the MagSafe leaving the battery disconnected. Your system should start wait till you get to your desktop and anything that’s auto loaded. Once everything has finished shut down your system and now reconnect the battery. Now this time restart your system, let it run for a good 5 minutes with the MagSafe connected and then take a fresh snapshot posted it here for us to see. Let’s see if things changed.

This is a battery I purchased on eBay and installed a week ago. My OEM battery was shutting down at 45%. When I get a chance to take the tiny screws out again, I'll follow your directions. Thanks!
