AGM battery on P2 models???

[Xand3r]

Hello everyone, need to replace the battery on my '05 xc90, 2.5T. Was thinking about an h6 agm energizer with the same capacity and RC, but with 760cca, sold at costco for the same price as the dealer is selling its oem, but with much longer warranty (5yrs full and another 3.5 yrs prorated). Now, the big question is: is there any problem if I'll put this agm battery, since the all system (meaning alternator and the cem program) wasn't "designed" for this kind of a battery. Have anyone had any kind of electrical problems. I know it should be plug'n'play, but the thing that the agm has a lower resistance doesn't make me sure on my choise. Thanks a lot everyone, best regards.
