94 cycles 98% Battery health? Good or not?

Hello everyone, I have 94 cycles on my macbook, and 98% battery. I currently have a macbook air through 130 cycles and 98% health also. Is this normal?

That is pretty good. I'm at 98 cycles and 91%. Apple claims 1000 cycles (on average) so anything better than 10 cycles/1% degradation is better than average assuming linear degradation.

How long have you had your computer?

I thought it was 1000 cycles before falling below 80%.

It is perfectly normal if your battery health (maximum capacity) is more or less than 100%, even when brand new, or if it fluctuates up or down over time. For further details, read the CHECKING STATUS AND HEALTH section of the following link.

The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

as long as its not below 80% before 1000 cycles your have nothing to complain or worry about, dont stress over watching the count/health ratio

It's not linear. It can fluctuate up and down.

Why? You're at 91%, well above 80%. Also, even when it drops below 80%, your battery is still usable.

I have 98% at 50 cycles on my rMBP (15" 2.7/16/768)... and the proper way to handle any Li-ion battery is a charge between 20-80%, havent been serious on that
an old Mbp (2009) we have has been seriously maintained, and its 1102 cycles at 91%

My 2010 MBP is running at 87% with 617 cycles at 30 months, its used everyday as my office computer and spends 8 hours a day on mains power and runs on battery all evening.

I seem to have an ok battery after all

Mine is the same.
I had a battery changed once that was at around this % at low cycles - considering taking mine back in again as it shouldnt be at 93% with such a low cycle count.

Seeing how mine never budges from 93% really (always 92-94%), I figure it is simply a case of the battery being ok but the capacity is off (as not all batteries will have the same characteristics)

cocunut batt seems to use a fixed value to calculate % health and that may be a misrepresentation imo
