OP in 2009 mention MF car battery last for 3 years. 

Its 2017 now, and in the past few years, my MF batteries don't last much more than 1yr.  Have had to change batteries for Kia Rondo, and Nissan Murano. 
Latest battery bought from random tire and battery shop only lasted 9 months.  Previous one just over 12 months.

Wanted to change to non-MF, but Nissan service center in JB only carries MF.

Yes mine too, BUT if the batteries left idle for say more than 5 days in my car then it will fall flat and need to jump start, then it goes back to normal.
