Hello, I see a lot of used batteries at various places, but I'm not seeing anyone with new batteries. I have a 500MHz model, and the battery charges fine, and I can get about an hour or so on it, but when it reaches 50 some odd percent (full or drained, your choice) it will suddenly drop to the red zone, and quickly go into sleep mode while working. I tried resetting the PMU last night to no avail, so I'm looking for a new battery. So, does anyone know of a good source for a new TiBook battery? Thank you, Alan
