Tha'ts old advice, based on the long debated theory of NiCad Memory. Several battery companies stated that it never occurs in real life but has been seen in such things a sattelites etc. But the advice is totally wrong with respect to Lith-Ion batterys. The Li-ion batteries prefer a shallow discharge. Partial discharges produce less wear than a full discharge and the capacity loss per cycle is reduced. A periodic full discharge is not required because the lithium-based battery has no memory. The links posted by SJB are excellent (although even they quote un-named "studies" supporting the NiCad myth.) -- ______________________________________ John Andersen NORCOM / Juneau, Alaska http://www.screenio.com/ (907) 790-3386 ._______________________________________ John S.
