Just sharing my thoughts. I have HP Laptop for 5yrs. I use that for 10hrs a day for 5 yrs, very rarely I use it with batteries I would say 95% of time my battries were 100% and power charger is connected and remain "ON". after 3.5 yrs HP/laptop software show indication of "END of life" for battery though to test I run my laptop on batteries and they work for full 3hrs as they used to work when new. but after another 6 months, i.e. 4yrs it won't work as long and by the time 5yr is complete it works only 20-30 minutes. But isn't it that good life for batteries anyways? and yes my charger were hot enough to cook :).
