Battery Guarantee

[Twenty1TEN]

I remember reading somewhere (please correct me if I'm wrong) that apple said their battery was guaranteed to a 1000 cycles before it reached 80% of it's original capacity.

At the moment my 22 month old unibody macbook has 83% left after 560 cycles.

Also two days ago when clicking on the battery icon it read 'service battery' that however has disappeared today, would it be best to be safe and go get it check out anyway?

Any help appreciated

Yes, 80% after 1000 cycles is correct. You're doing better than me though, 72% after 547 cycles >.<

haha wow good effort.

So what if it drops believe 80% before 1000 cycles are we warrant for a free battery replacement or do they still charge you..I don't have apple care.

Actually, don't take the capacity readings too seriously, Watts (app) is now reporting 67% capacity. Definitely calibrate your battery before thinking too much about capacity readings (I'd recommend Watts to help with calibration, if you don't mind paying for it).

I'm honestly not sure about replacements, never bothered looking in to it as it doesn't bother me (my MBP has never left the house).

This should answer most, if not all, of your battery questions:

The 1,000 cycle battery life is true for the 2010 and 2011 MBP. Early models have a 300 cycle battery

Thanks everyone for your replies

I have the mid-2009 MBP model and am at:

665 Cycles

85% Health

I remember the 2009 models were featured as capable of holding 1000 Charges.

Guess if it drops i'll be taking it to Apple. either way, at 1000 cycles i'll be getting a new battery.
