Michel: 17amp or less has been history for some time. I still have
        a black tekna among my scooters and have been using the
        12v 18 Ah cells for several years.
        Recently, I upgraded to the 12v,20Ah from "PB" which
        are markedly superior......upgraded to
        the PowerSonic 12v26Ah for the Zepps while I was
        at it.
        Yes, I'm sure AUL can get you the Tekna paks that you need.
        Their site is at www.aulinc.com
               Safe diving.......D.
