    Ok, techie wizards, what's the difinitive word on conditioning a new laptop battery? Is it true that fully charging and then fully discharging the battery a few times will help extend its life? Is this true or urban myth? I just got a new Dell and want to do the right thing.

    It is not urban myth....Dell even recommends it.

    I have also heard that those under laptop fan platforms help keep the battery cool, thus heat shortens battery life.;f

    Depends on the battery type. Old fashioned nickel-cadmium batteries should be fully discharged, and then you should fully charge them. If you don't, then the battery tends to build up a "memory" that artifically shortens its charge remaining, although this memory can be removed by fully discharging and fully recharging a few times.

    Nickel-metal hydride (NIMH) batteries are also capable of building up memory, but they are more resistant than their inferior NiCad counterparts.

    Lithium-ion batteries supposedly do not suffer from "memory."

    Here's an interesting read:
