Coconut Battery app discovers a gem ;)
I have noticed this on a few occasions that CB (latest build & on previous builds) will give a date of manufacture that pre dates the unit itself..... This particular example is for a new battery installed on a MB Air A1932 which 1st appeared in 2018...... I have also noticed this on some A1278's, A1465's & 1966's that a new battery was made 10 years back which is highly unlikely. I have run CB from applications and externally to see if it made any difference. What causes this? A software bug or a battery manufacture cloning the battery chips? I recently bought 3 Air batteries from the same seller and 2 stated made in 2024 and 1 was 2015.....so cloning may not always be the case....
Seems someone else may have had the same thing
Replacement battery age requested before purchase
System Report Vs Coconut Battery.. (Battery purchased Oct 2024 as new)... 2014.

@livfe have you noticed any difference on this data while testing OEM batteries vs aftermarket? If this is a software bug then it should give you a "weird " manufacturing date for both. If it is based on a cloned battery control board it should only show this date mismatch on aftermarket products but not OEM. It's those dumpster diving chinese that are causing the mismatch and have been doing this covertly for decades /s SMH

@oldturkey03 Strange that 1/3 said 2015 (The other 2 said 2024).

@oldturkey03 @danj Check out the latest updated Picture ;)
What would you trust more, Apples System Report or Coconuts?

@livfe - Where is the Design Capacity value in Apples Battery data? Mmm
Maybe the question is why Apple doesn’t offer it! Only offering a simple statement not a graph to know the wear level.
As I’ve used CoconutBattery for years and helping many people here and when I was working full time repairing gear I have found CoconutBattery invaluable and fully reliable.

@danj Yes I also used it for many years, Apples says normal good condition and Coconut give a check battery warning.... we checked it, all connected fine and charging etc.... very weird just 11 cycles and this.... mind you, I have another 'New' battery with 1 cycle that refuses to take a charge on the same Macbook :) Coconut reported 0 capacity!
