The new battery lasts very little
For some time the original battery replaced just over a year ago has started to last very little. After about 2 hours, in fact, it was already discharged (with a non-intensive use of the PC) when before the duration was around 4 hours.
So I decided to change the battery of my MacBook Pro with the kit proposed by IFixit but even after the change the duration has not changed.
The hardware test returns the error PPT0004 and I don't know if it is a true error or due to the fact that the battery is not original.
How can I check if the new battery is fully functional?
Checking the battery consumption from the system I do not see particular anomalies of applications that can consume more energy than expected.
Anyone have any ideas?

@mayer - I have created a bootable usb and installed Coconut.
