Hi, I have asked before about the rebuilding of 2400 batteries, with ABSOLUTELY no response! I guess I'll have to investigate it myself, but I only have working batteries. Does anyone have an absolutely DEAD 2400 battery they'd part with for me to experiment on? Is there any good software to extend the life of the 2400 battery? Does anyone know what size, type, etc. of cells are inside the 2400 battery? TIA. Paul
