    It's complete BS as far as I know...

    From Interstate Batteries FAQs  "...Interstate is the world leader in battery quality with 80+ years of innovation. Interstate Batteries, manufactured by Johnson Controls, are the #1 automotive replacement batteries in America with 15 million batteries sold every year."

    Then again Interstate Battery  is a marketing company which manufacturers nothing,  but rather put out tenders to see who can supply the lowest cost to maximize profit. To find out who the actual manufacturer is, one could request a material safety data sheet, which will list the manufacturer, Johnson Controls had been the supplier for some time but who knows what happens in the corporate world.

     As a side note, years ago a marketing company approached us with a low cost alternative to the SLA Panasonic batteries we used in fire alarm, security and emergency lighting, we used thousands annually,  initially they were satisfactory but later they had a high failure rate. Turns out they had switched supplier in China who filled the bottom 30% of the batteries with sand to save on lead costs, it's all about money.

    I suspect that you are correct. Trojan is working hard to repair/improve their image and market position. Interstate very effectively penetrates the lower end of their market segment with heavy marketing - clearly not where Trojan lives.
    I always have more questions than answers. That's the nature of life.

    Hey Marc !  How is the lake? Been some time!

      I think Trojan needs to work alot harder!  They are still selling one of the lamest 2V LA's in the world. Have to check and water 3 separate cells in a 2V battery. Been doing this for over 12 years....Think how many people get stuck with 72 cells to maintain over 24.

    It is enough to make you go to AGM ;)     Good documentary on the ZTop on netflix.   Cheers in advance!
