Battery Help

Looking to put 4 6volt Trojan batteries in out 5th Wheel. I’m looking to the T105, T125 and T145. What would all of you suggest? Thanks!
  • I have the T125s, been using them for six years and they've done well. But, I must say you'll pay like 25% more for them over the T100s, but only get about 10% more amp hours. If you boondock a lot, it's probably worth it, but not if you spend most of your time plugged in.

  • 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.
  • I'd like to see you try the AGMs. So nice to not have to water the darn things.
  • Choose the jar that will allow for the greatest number of amp-hours @ 12 volts, without exceeding the weight carrying capacity of the compartment.
