Does anyone know why the hack (covering middle contact of NB-5H battery supposedly "extends" battery life/charge 10x) described by the OP on this website works -- http://www.diyaudio.com/forums/showt...?threadid=7550 ? Has anyone else tried the hack? Are there any obvious dangers in doing the hack? Would I be risking damage to the rechargeable battery, camera and/or self by doing this hack?
