Every Toshiba PA3399U-2BRS laptop battery should be under strict quality control including filtration and safety testing of voltage,capacity and battery core before leaving the factory, and has passed the authentication of CE, UL, EMC, CQC,ROHS, etc.
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 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.

It fit in my wife's laptop just fine. Took a charge and holds it. Far cheaper than the official replacement.
The batteries in general for this model seem not very good, if this lasts a year I'll be happy.

I get about 2.5 to 3 hours, compared to barely 1.5 to 2 hours with the OEM battery that came with my Toshiba laptop.
