The T125 and T145 hold a little bit more energy, but you will pay a lot for it ! T105 are more common and you will probably get them at a much better price.
If you really want to save a few $$$, get Interstate GC2 at Costco or Duracell GC2 at Sams Club. They hold a bit less energy, but are much more "cost effective" ($$$/A-Hr @ 20Hr rate)
You pay a lot of extra $$ for T105-AGM and lose a bit of capacity.
