I didn't abuse it , charged mostly on l1 and l2, never drained all the way, DC charged rarely, I still have something left of my promotional 250 kwh of Electrify America. It was ok for more then year and a half. Charged to 91-92kwh no problem. and suddenly this leap happened. 87.5 and not charging anymoreThat's interesting, and surprising. How did you measure this, if you don't mind?
A popular YouTube personality in the Bolt community didn't get called in for his battery replacement until 154,000 miles and six years of abuse, including frequent DC charging and drains to a very low state of charge.
He knew his viewers would be interested so he drained down to zero and DC charged to full.
He lost only 10% of his OEM 60 kWh battery in all those miles, with all that abuse.
So I'm surprised that a Mach-E with a similarly conventional NMC formula would lose that much capacity so early in its career.
However, we should mention that Tesla NMC batteries seem to lose about 10% of their capacities in the early stages of ownership, and then slow the rate of depletion.
