The equivalent of a full charge and discharge. It's how they advertise
their batteries.<br>
<br>
I work on the assumption that it costs ECS about 10p per hour to run my
Mac on battery.<br>

Interesting.
I have two batteries - The one from 2006 reports 107 cycles, and the one
from 2007 (which I use more) reports 159 cycles.
Seems pretty low to me, for the only machine I use.
I wonder what a cycle is.

<pre wrap="">Well, that was a waste of time. Turns out that the "Geniuses" will
not carry out a warranty battery replacement if your charge cycle
count is over 300. Say, if you've been using the laptop daily for a
year. (That mine is as low as 443 after two and a half is somewhat of
an indicator that I've been using old ThinkPads and the trusty EeePC
instead.)
For those wanting to avoid fruitless trips to West Quay, dashboard
widget iStat Pro can show the cycle count; so can a standalone tool
called Battery Health Monitor.
Needless to say I am not impressed, and given that the "genius'" part
in this was to boot off an iPod which made "battery consumed" appear
on the screen in a big, red rectangle, I wasn't about to argue the
point that it's been cooked for quite some time (literally, I fear---
I suspect the capacity loss is actually thermal). Presumably if the
hard drive died I'd be told it's out of warranty because I dared to
store files on it.
