Lithium-Ion batteries simply have a short life. The common rule of thumb
is 20% loss of capacity per year - whether it's used or not - and
another 20% per 100 deep cycles. These figures get a lot worse with
increasing temperature.
I bought my laptop 3 years ago, and the battery was probably already at
least one year old. Add in some 300 deep cycles, and we're down to 20%
of its original capacity. When it was brand new, it only did about 50
minutes, so now I only have time to get the mains lead out!
Curiously enough, the industry doesn't advertise this "feature".

Similar situation and response from me, I'm faced with shelling out
$375 ( !!! ) for my Acer's battery replacement, 2 years old and
lasting 15 minutes. Have had the same place recommended to me as a
cheaper (but still not cheap) alternative, and just as soon as I've
got a spare couple of hundred dollars I'll get mine done - or maybe
I'll just put a down payment on a new laptop.
I never thought of looking into battery reliability or replacement
cost when buying it but won't make that mistake next time . . .

There is a place in Gasson Street, Battery Masta I think they are
called.
No personal dealings, but have made enquiries a few times. Not cheap,
but neither are the "official" replacements.

Just had to get a new battery for the tosh... the 2.5 hours of stated

Is there anywhere I can take the old one to get the cells replaced?
It's a
li-ion battery. I'd rather use someone who people have had dealings
with
for obvious reasons!
