PSP Hardware Cleaning Guide

I'm pretty sure that doesn't apply to PSP batteries. You're thinking of the old "memory effect" on rechargable NiCad, where they'd charge less if you didn't fully discharge them. PSP's batteries are Li-Ion, which are completely unaffected. In fact, I think they may actually benefit from being kept full.

I guess you're right, I found this tidbit on the net regarding care of Li-Ion batteries...
Lithium Ion (Li-On.) battery---
Lithium Ion battery doesn't have "Memory" problem either, You may go back to recharge this kind battery at any level you want to. You shall not use the discharge function button on the charger to discharge a Lithium Ion battery.
This kind battery is much lighter, require much less space. So they can contain much more capacity than a Ni-Cd or Ni-Mh battery. They are representing the newest trend in the battery business.

Here is the routine process to take care a Lithium Ion battery--
After you use it, you may go back to recharge it at any level you want to.(A.S.A.P.)
You shall not use the discharge function button on the charger to discharge a Lithium Ion battery.
After fully charged, take the battery out of the charger base, keep it in the shelf.
Every 30 days or so, even if you don't need to use it, You still need to bring it out, and recharge it. Because every battery will self-drain the power from 1 to 3% on the daily base. By the 30th day. The battery may down to zero already. That is the time battery getting hurts.
Lithium Ion battery only can be recharged up to 300 to 400 times.

Actually the best thing to do is give it a full charge out of the box. The batteries need a few good cycles to establish a good memory.

lithium is much lighter and lasts alot longer...everything else still applies
