Mac turns off with low battery
Hi guys. I bought a new battery spare on iFixit and I've install it on my mac. Everything is apparently ok.
But it happened to me that the battery level was around 14% and the mac turned off without any screen message. It did want to turn on until I connected the magsafe. Unplugging the magsafe caused another immediately shutdown.
So i left it plugged for some time and now it is properly working.
Suggestion about which is the problem affecting my new battery? Thanks

Guys, thanks for replying me.
Well, I did the SMC reset procedure as reported by Apple (connecting the magsafe, i pressed control-alt-maiusc at the left of the keyboard and power at the same time). I was sure the procedure got successful because the magsafe led turned green and then orange again.
But apparently this not worked in my case.
So i decided to open again my laptop and I performed the procedure reported not for Macbook Pro, but for the MacBook, i.e. I removed the battery and pressed power button for >10s.
Now it properly works! This laptop will never die!!!
Thanks again

Hey guys. I've got a new problem now.
After some days, I've got again the message "battery requires assistance".
What's wrong now?
This is the screen which reports the battery information: https://i.imgur.com/3MDbIGb.png
Some suggestion? Is the battery that iFixit sold me not good?
Is dit een goede vraag?
