Did you or anyone ever get an issue like this sorted out?
I have a seemingly good battery (according to coconutBattery) of the same Simplo brand that won’t charge.
What I find so odd is that changing back to the swollen original Apple battery the machine will charge and run just fine of the battery, only problem is that it’s so big and swollen now that it’s nearly twice it’s intended thickness.
This makes me suspect a faulty battery even if coconutBattery indicates it being good, perhaps an issue with the battery brand???
