i understand that battery health fluctuates over time or is not at 100%. my battery health is 91% with 104 cycles with 7775 for max capacity. my capacity was never near the 8400 design capacity. i just hope it stays near 90% for a while. at 80% the battery is replaced and i hope that is years from now not months.
