The more you charge/discharge batteries, the faster they get 'worn' out. bad idea. your experience with the other laptop was prolly due to the fact that the laptop was running on full perf mode on AC, and very hot. High temperatures cause battery issues as well.
Anyway, running the laptop off battery is obviously inefficient in terms of power consumption and all, Greenpeace might try to block your program if it becomes popular :D it is best to keep your laptop on AC power all the times!
