work for main batt?

thanks, it jus seems to beat the hell out of an optima plus its just as good i would think as my crappy battery plus 5caps for the system so until i can get 2 more of these for the back atleast one in the front would be way better than current one! does anyone here have experience wit powermaster batts? or alts cause jegs gots a 170amp powermaster alt for my jeep for 450ish, or ebay got a 160amp for 150, or a 220 for 220! but i dont trust the ebay ones lastin long or puttin out that many amps at only 1800rpm, more like 200amps at 12000rpm and 50 at idle!
