Could be a two-sided story. Most dealers I know buy cheap ass Chinese Batteries. Holes in the story; or Holes in the can...what's it matter.
I have installed mini computer fans with a mini temp sensor in commercial panels & power supply cans for years. I don't use the cheap batteries, but the cheapest battery I will use is the ELK. Other than that, Yuasa batteries really can't be beat.
