Replacement battery not holding charge
I recently replaced my 2011 MacBook Pro 15” with a battery purchased from ifixit and following the online instructions. Got it up and running fine but the replacement battery is very slow to charge and runs out of charge in around an hour and a half once disconnected from the charger. When setting up I also followed instructions to yield the best performance from the new battery. So I’m wondering if there’s a fault with the new battery?
Is this a good question?
