AGM batteries are really fussy about the way they are charged. Personally, I would never use one in a motorcycle. They may be better these days, but they dont like ripple, which is the essence of most motorcycle chargeing mechanisims, especially older ones.
Problem with a lot of bikes, is use cant use a wet cell battery cause they mount the batteries in wierd ways.
As for car chargers, if its the old arlec style 4A transformer type, then bin it. No good for charging small batteries. Find a charger suited to AGM's and GEL batteries.
