Query: Great Quality

I was pleasantly surprised as to how long the battery charge lasted. I am running Windows Vista 32-bit OS and with my wireless turned off and the display brightness down on my Satellite A105, the battery will last 3+ hours. If you are looking for a good replacement for your Toshiba battery pack, I recommend you stick to this factory replacement. Hope this helps inform your decision a little better. Good luck.
