I need a new group 27 battery for the Fury and was all set to plunk down the big bucks for one of those AGM batteries that supposedly last a LONG time and never leak. Then I started reading more about them.
They don't like fast charging and like a lower charging voltage. Newer cars supposedly can sense what type of battery is put in the car, and adjust charging accordingly. But our older cars can't.
Bottom line seems to be that if an AGM is treated carefully, it can last a long time and supply a lot of starting amperage. If it is NOT treated just right it will not last any longer than any other battery.
For occasional use, any type of car battery does better if it is maintained on a trickle charge rather than let run completely down and recharged at a high ampere rate.
I am thinking it may make better sense to buy a traditional battery, even a retro-look, and maintain it by a trickle charge. Lots of people say they've made a conventional battery last 7 years with good care. Heck, it has happened once with me.
