I think all laptops can extend the battery life-span significantly with just smarter software. I manually cycle my laptop battery regularly & do not keep it charged at 100% all the time even if the laptop is plugged in (some Thinkpad models allow that). Even after 2 years of daily use, I've got greater than 80-90% battery capacity left.
