Also, not sure if this is possible, but I would like to control how the laptop charges the battery. I tend to have the laptop plugged in most of the time and this constant charging state is apparently very bad for battery lifetime. So a charge/drain cycle is supposedly better.

assuming a reasonably modern (last 5 years?) laptop with a lithium-ion battery, your battery's useful life is the shorter of

~400 full discharge/recharge cycles (+/- 200) 3-5 years from date of manufacture

after that, the battery charge will last about half as long as when it was new, and it will continue to deteriorate.
