Read the original article Hit count: 192

Is that dangerous :

  • for the computer (without the battery)
  • for the cells

If possible, explain why.

Edit : Here are some more assumptions : Without the battery included, there is no risk of overheating the cell, or over charging them. But there is still some dc to dc conversion taking place on the motherboard. I assume this dc to dc stage to be quite tolerant. What kind of trouble can I run into when using 20V instead of 19V ? Overheating ?
