Just replaced the battery with a new one from IFIXIT
I just replaced my battery on my MacBook, with a new one, kit from IFIXIT
Battery works fine, lovely kit to do the replacement.
But now it says that the battery manufacture date is 2012-10-24.......
Thats even older than my original! I just replaced.
Can this date be changed?
I've posted a followup question for the IFIXIT Store here: Battery kit battery date mis-set?
I personally don't know if the batteries EEPROM date can be changed. Keep in mind the battery unit is used in quite a few systems. So its possible this battery assembly maybe older than your battery, LiOn batteries do have a long shelf life so I wouldn't be too concerned.
