Dustin,
    As usual, you do not know what you are talking about. The batteries =
currently being used in DV-100, DV-3X, and Mako are a 17.2 amp.hr. =
battery. To use the term 17 amp.hr. is correct. Many battery mfgs. use =
the label of 18 amp.hr., but they are still 17.2 as stated on the side =
of these batteries. To tell people the the 17 amp.hr. has been history =
for some time shows how uninformed you really are. I am sure you wanted =
to say the 15 amp.hr that came with the original DV-3X has been history =
for a long time. People believe that somehow you can put more amp.hr in =
the same size case, but that would be like putting 22 gals. in a 20 gal. =
fuel tank. I have even seen batteries with 8 amp.hr. written on them =
that are the same size as the 7 amp.hr. batteries in use in most primary =
lights. This is simply a lie. The 7amp.hr. battery is really only 6.5 =
amp.hr.

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.
