the batteries will outlast the laptop so it makes no difference.

to put it another way, you'll be wanting to replace the entire laptop
for a newer and faster model before the battery in the old one needs to
be replaced.

no koolaid needed.

the batteries are rated to last 5 years with 80% capacity. most people
replace their computer every 3-4 years. 

even for those who keep their laptop a bit longer than typical (which
is a minority), the battery is still plenty usable, especially when it
originally lasted 10-12 hours. 

worst case, break out a screwdriver and swap the battery or take it to
an applestore and let them do it. it will only need to be done once in
the life of the laptop. 

plus, it's not just apple with internal batteries either. 

it's a complete non-issue.

That is rather optimistic. lithium ion battery chemistry degrades over
time.  Apple still has to live within the rules of physics and chemistry.

My MacBookPro had severely degraded after 4 years. Not even close to
having kept 80% over 5 years.

Which is why there is no point in making unreal claims about Apple's
batteries lasting longer than lithium ion batteries. Everyone on same
footing here.

More generic FUD spreading. The batteries are rated for 80% charge
capacity at 5 years. You imply by your FUDish statement that these
numbers aren't correct. Put up or shut up.

First, different and older battery. I doubt it was rated for 5 years. Probably 3.

There was no such claim, you liar. The battery is rated for 5 years. Fact.

The Apple claim is 80% after 1000 complete charge cycles (for Macbooks). 
  So depending on the user that could be less than 3 years 
(balls-to-the-wall road warrior) or much many more.

For many (probably most) users 5 years is a pretty good bet.

True, though I think it is 1000 charges OR 5 years. That is, even with a
low charge cycle count, the battery will lose as much as 20% efficacy
after 5 years.

1000 cycles will take long on the MacBook than on the other machines
because each cycle is much longer (twice as long as on a 4 year old
MacBook Pro, for example).

I replaced my battery on this 2009 MacBook because it was barely lasting
2 hours (sadly, out  of warranty) 2 years ago. The new battery has 411
cycles and a capacity of 5100mAh. I use the laptop every day for at
least an horu or two, and sometimes for 5 or 6. It goes about 4:30 from
full charge unless I play video in which case the power goes to hell.

> For many (probably most) users 5 years is a pretty good bet.

Yep, I bet most MacBook buyers will be well under 1000 cycles at 5
years. Based on my current usage, I'd be close to 500.

lots of hand waving and blah blah blah

1000 charges
what about discharges
and what's the definition of a charge
or a discharge

and why would aapple ever replace a battery free of charge (pun)
are some defective and overly free of charge to a fault
are aapple so kind/generous that they just feel need to give back
does the batt supplier suck up the loss

it's all rather odd 
i smell a cover up

perhaps the charge/discharge technology in the laptops was defective
but since it was firmware/software fixable they said "well we'll replace
some of them if it's normal wear/tear" (whatever that means)

deflect blame
move along

These days it's usually defined as complete charge-discharges cycles. 

If you let your battery run down to half charged, then plug it into the
wall to recharge it, you can do that twice before it counts as "1
charge cycle".

If you let your battery run down by 10% and then recharge it, then you
can do that 10 times to count as "1 charge cycle".

BUT leaving your portable device plugged into the wall constantly is
not a good idea either (even ignoring the fact that it was pointless
buying a portable device in the first place).

Batteries are an old and crap technology - they were hopeless long
before laptops were created and still are (one reason why electric cars
simply are not a solution to anything). 

The fact that all batteries do become useless is used by people jumping
onto the portable device fad  ... it gives them a "good" excuse for
throwing away otherwise perfectly good equipment and buying a new one.

I beg to differ.
My MBP is almost constantly plugged in and hooked up to a Monitor.
About once or twice a month I take it with me.

Worked fine for several years and still held enough charge to last a
working day when I got a new one last year.
I´m pretty confident this will last about 5 years before I buy the next
one. (And if not I´ll simply have the battery replaced by Apple.)

I just don´t have the time to pamper my battery and try to "optimize" it
by letting it run empty every other day or by any other means that
supposedly prolong it´s lifetime.

That sort of usage pattern is fine.

Problems can start to occur if the battery is not exercised for several
months to years. I've seen a few cases where someone had a MacBook that
almost never got unplugged from power, and they were surprised to find
that the battery didn't hold much charge when they came to try using it
after a year or two.

Using the computer on battery once or twice a month should be enough to
keep it healthy (running to empty would probably be better, but even
some battery usage is better than none).

Running empty every other day would be excessive. Apple recommends
letting it run empty every month, and that's mostly to calibrate the
battery level measurement. I don't bother, nor do I know anyone who
does.

My typical usage pattern is to have the computer plugged in on weekdays
while at work, and if I use it at home or elsewhere in the evening or
weekend, it is mostly running from battery, except where I have used it
enough to need to plug it in, or if I'm doing something more intensive
that justifies working at a desk or table.

I had each of my previous two MacBook Pros for three to four years and
they still had several hours of operating time on the original battery
when I sold them (both to people I know, so I've had occasional updates
about their current state).

The older one had a removable battery, rated for 80% of its original
capacity after 300 charge cycles. It was up to 450 charge cycles when it
was approaching three years old, and I didn't notice much drop in
battery operating time. The new owner never replaced the battery and it
was still good enough to be useful after seven years. Unfortunately the
computer suffered an accident about then so the experiment can't
continue.

The newer one had an integrated battery, rated for 80% of its original
capacity after 1000 charge cycles. I didn't note where it was when I
sold it, but a sample at about the two year mark shows I was using about
150 charge cycles per annum, so it was probably around 600 when I sold
it after almost four years. The new owner now has it plugged in all of
the time, which is probably not good for it.

I seem to be using the battery a little less on my current MacBook Pro:
about 110 charge cycles per annum so far. The battery operating time is
longer on this model, so it may be that I'm using it on battery about
the same amount but that isn't discharging the battery as far as with my
previous one.

this is important because it's clear that aapple tries to cater to
the lowest common demoninator of consumer, not all people care
about things like battery pampering and aapple doesn't want them
to have to think about those details
the firmware/software needs to be better to eliminate any need to do
this

for example why couldn't the laptop while it's plugged into AC
still go through a close to full discharge once in a while
if that's needed

not only is that not needed but it would be a very stupid thing to do.

no product does that.

It does not go to full discharge but it is not constantly charging
either.
AFAIK if the battery is at 100% charging stops until the charge drops to
98% and then it will be charged again.
Someone please correct me if I got this wrong.

you have to discharge before you can charge. duh.

more duh.

These are well-defined. Your ignorance can easily be solved with use of google.

you deteriorate so quickly into personal attacks and foul
language like many others here

it's embarassing to witness and it's expected from a losing position
lashing out in fear or something

Its not a personal attack. You've ha this pointed out to you many times
by different people. You still haven't figured it out.
