Hey all So I got a second hand original battery because mine is quite swollen at this point. I can’t power it up after I changed it from the power button. If I disconnect the MagSafe charger the Mac shuts off. After replacement I hook it up to the MagSafe charger and LED’s are orange -> green -> orange Mac says “replace now” etc. Tried SMC/NVRAM reset to no avail. when I swap my original battery everything is good.
Sadly your charging logic on you main logic board is damaged.
