What are folks recent experiences of laptop battery lifespan??

We're starting to find that laptop batteries are dying after just 18 months
on our 2009/2010 hardware.  This is a mix of brands (mainly acer and dell),
and the use has been varied from heavy daily cycling to others than have
spent the entire time on the mains using laptop risers to keep them cool.

Our older laptops still hold a usable charge after 3 or 4 years.  What's the
deal with these newer ones?  Has Li-ion changed? Is it Windows7 or are we
being had by manufacturers?

Have any others found this?
