I had bad luck with Interstate 12V
over the years on 3 of my AS's when I took delivery new, but Interstate did stand behind the warranty and replaced for free; now I use the T105 Trojan 6V wired in parallel and after 6 years, still going strong. If I were using 12V
again, I would either get the 12v
Interstates from Costco or 12V Duracell from Sams, or Walmart batteries and be done with it. All 3 have good warranties if you want to stay with 12V's.
