Laptop:  Sony VGN-FS550
Battery:  VGP-BPS2A   11.1V/4400mAh

1.  Is it okay to replace the dead Sony VGP-BPS2A 11.1v/4400mAH, with
a generic VGP-BPL2 with 6600mAH?

2.  Will the 6600mAH give longer life at one sitting without harming
the computer?

3.  Are all generic batteries on the market today to be trusted,

The Sony battery is dead, and it never gave me more than about 45
minutes max anyway.

Generics are hit and miss. Then again, Sony had all those fire hazard
batteries (there was (still is?) spectacular footage posted on youtube
and other video hosting sites of this in action). And was reluctant to
recall them. I suspect many defective Sony batteries will not be

6600mAH would provide you with longer battery life than 4400mAH.

If you can supply us with the maker of this generic battery, perhaps
someone can tell you whether the maker is reputable or not.

FWIW,  You can hardly do WORSE than the previous battery.
