Improve your iPod's battery life

Echo Mixed Nuts reports an article from CNet on tips to improve the battery life for your iPod. It presents a view different from what I had always thought.

The article says that you must never let the battery die completely, and should recharge it to the fullest every now and then. But that was not what I had known till now. I always thought to maximize battery life, you need to discharge it completely before recharging it every time..

I now need help!!!
