This is the agm in my truck, it just has the pop offs for each cell, been in my truck for atleast 6 years, just took the terminal off so the battery doesn't drain dead with brake lights, I am changing out the power brake booster, so pedal is loose and brake lights would be on.
Never coated the terminals or done anything to them since sealed batteries.
Would like to see a standard flooded battery that has terminals this clean without treating them for this long.

The agm in my golden jubilee tractor, the battery gets rained on and terminals just as clean.
