MacBook Air 2011 Battery

Hi, I recently bought a second hand MacBook Air 2011, it was virtually brand new.

When I bought it I ran some quick tests on it, the battery had around 180 odd cycles. It now has 191 cycles and I am wondering:

a. How long should my battery be lasting at this state?
b. When does my battery need replacing (or does it?)

Thanks in advance!

Hi minecraftman,

Can you do this one thing please and then see what the figures are afterwards...it might just need recalibrating.

Apple Portables: Calibrating your computer's battery for best performance

EDIT Whoops I'd no idea that batteries in the Macbook Air cannot be recalibrated!! they are apparently 'pre-calibrated'

Still if you have a look here http://www.apple.com/batteries/ this will give some brief background. I'm only speculating here but you might have introduced a more efficient charging regime henceforth the improved 'remaining' cycle count. That figure is normally plotted against the battery's full charging capacity falling to around 80%...it's not going to just stop working when it falls below that capacity.

Thank you very much anyway. (I see your name is pendlewitch... I ski twice a week at Pendle Dry Ski Slope!!!)

Lol! This is really a small world..I just had a PM from another member who is also very close...perhaps we should form a coven?

I dabbled with skiing for a while and went to Les Gets several times which was fantastic...you're more likely to see me out and about with my Pendle Forest Cycling Club kit on though..I'm more comfortable on a bicycle.

Cheers,
Liam

Lol, I'm that other member and the last time you tried that, pendlewitch, you all got burned at the stake!!! I'll pass
Sadly my aging knees can handle neither cycling nor skiing
Can just about manage golf on a good day

Mac notebooks: Determining battery cycle count

FTA - You should be good for ~1000 cycles before the battery is considered consumed.

Here is the replacement FAQ from Apple £99 with VAT

But if you are a diy type of person there is plenty of information on how to replace the battery on the Web.

Hmm, we're in the North of England - who mentioned dry?

minecraftman did - and so did the website
Pendle Ski Club

But I'm guessing it is dry in the academic sense being North England.

Just joking, dry is a relative term when we talk about the north of England in recent times
But I get your point
