I don't really think there's a cut and dry method of conserving battery life. If the battery is a NiCad certainly you can't discharge it until its almost beat, besides I don't think the computer will like it! Nickel-Metal Halide is better and a Lithium Ion is th best. Operate the laptop with the ac adapter as much as possible. When the battery is on charge don't let it heat up! Unplug it , let it cool down then put it back on charge. Oh yes check your cmos battery once in a while. When your on board clock starts to lack in time, time to change the button cell.
