how to prolong laptop battery lifetime?

Archived from groups: alt.sys.pc-clone.dell (More info?)

I have a desktop replacement dell laptop (inspiron 8600). When I use it at
home, what is better for the battery?

- charge the laptop until it is full, then unplug and use it until it is
almost dead, then plug it in again ...
- keep the charger plugged in all the time
- use the laptop with the battery removed and keep the battery fully charged
- use the laptop with the battery removed; don't keep the battery fully
charged

NEVER deep discharge a lithium ion battery - doing so even once can
permanently damage it.

Li-ion batteries work best when topped up regularly. Whether you use it
or not, it will eventually deteriorate from age - 300-500 charge cycles,
or about 18 month-2 years before many no longer hold sufficient charge.

Of course I do full charge/discharge cycles!
