[W126 Coupe] AGM Battaries

[calvin young]

Where does one get the AGM Battaries?  Sounds like a smart decision for a 
car one plans to keep and for new vehicles.  I have a 2002 caddy with 
battery in the trunk and the post broke off without me every touching the 
thing and of course got al kinds of acid in the space below the seat which 
had to be neutralized and then primed and painted.  Huge pain for no 
additional value added to the car.
