Chosen Solution
Hej all together, I’ve a huge problem with my changed iFixit Battery. I can’t reset the battery properly. This means even if I have 15-18% Battery left my MacBook Pro shuts down immediately. Not very nice at all. What I’ve tried was following the Apple advice, to empty the Battery and wait and the recharge it… Did it a couple of times. 2nd what I’ve tried was to reset the SMC, doesn’t work either. One small note. The LED from the charger doesn’t work properly from time to time. And when my MacBook is open and I try to put it into sleepingmode it wakes up after a few seconds. Maybe this does help (I haven’t a clue). If you need further information just let me know (or any translation) I’d be grateful if there is someone who has a idea :) greets, Jonas MacBook Pro 13" Mid 2010 Informationen zum Batteriemodell: Seriennummer: DHersteller: SMPGerätename: bq20z451Pack Lot Code: 0PCB Lot Code: 0Firmware-Version: 74Hardware-Version: 00aaZellen-Version: 2 Informationen zum Ladezustand: Verbleibende Ladung (in mAh): 1656Vollständig geladen: NeinBatterie wird geladen: JaVolle Ladekapazität (in mAh): 6261 Informationen zum Batteriezustand: Anzahl der Zyklen: 72Zustand: GutBatterie ist installiert: JaStromverbrauch (in mA): 2885Spannung (in mV): 11734 Update (25.04.2017) I cleaned the port and bought a new cable. But, I still have the issue. I saw that during the loading process the Battery charge jumps from 81% to 100%. Until now I saw it only once.

@xco Hi Jonas, Can you tell us your usage pattern. Do you tend to travel running the system on battery until it has exhausted? Or, are you using your system mostly tethered to the MagSafe charger? Why I ask is for such a young battery you have already pushed the cycle count to 111. The status of the battery & charging looks healthy otherwise. The only thing I suspect here is you weren’t able to get the system to reset the SMC for some reason. Here’s the Apple T/N: Reset the System Management Controller (SMC) on your Mac I’ll let you in on a secret ;-} Even I’ve had problems getting it to reset if I rush it. You see, the trick is to full discharge the system so the older setting is forgotten. There are two pieces that need clearing the logic board and the battery its self as it has a chip onboard as well. So you need to hold the keys & power button a good 15 seconds (longer than what the TN states). Don’t forget to first fully charge the battery (overnight) then do the SMC reset, then fully discharge the system (I run a script doing a heavy action over and over again to speed this up a bit and I have it save the count of cycles). Then I recharge the battery (overnight) and then run my script again. But this time I review the counter it needs to be within the same value I’ve listed for the given series if not I’ll put in a new battery and then repeat this process again. What have I learned… First not all battery suppliers have good products! I’ve gotten a few defective batteries even from our trusted source. Sometimes it’s the system not the battery, either the MagSafe connector or the logic on the system board.
You said the charger light doesn’t always work, do you have a spare charger to test it? That could be your problem
