Technical Anyone Using AGM or Lithium Ion Car Batteries?

None of my cars have an AGM battery in them but I've had my ION one for some time...…..
Oh jeez, sorry! That was just hanging right out there, I had to.....

 

Being retired from Freightliner, I've been through all the battery combinations on heavy trucks. Deep cycle batteries, AGM, combination of deep cycle and normal batteries and normal lead acid batteries. I'm sure that some companies fooled with capacitors, but they never proved out. At least 98% of trucks built are running multiple batteries.
