Thanks Tonny,
checked out the two batteries and the 6 cell looks the same as mine whereas the 12 cell has a different casing/shape but as you pointed out and the website says, should be compatible with Satellite U500.
I would be interested to know how much added time I would get from a 12 cell compared to 6 cell. Going off the mAh's (7800 vs 4700) should get 60% more time on 12 cell. Just wondering if it's worth the cost.
Food for thought.
Thanks for the help
