There's a very good reason why most people think AGM's suck.
If you flatline them, good luck re-charging.
If you charge over 16v for any amount of time (which means ever) you kill them. Even 15.5v for any amount of time is bad.
Most stock alternators/voltage regulators WILL kill AGM's.
ie: to do AGM's right and have them last more than 2 years (which seems to be whats happening, my father just replaced a bank of AGM's that were almost 8 years old now, funny how things work right when set up right) you need to be running a GOOD alternator and a GOOD voltage regular (best? Balmar, but not cheap.).
So basically, unless you want to set it up right, and spend alot of money doing so, go buy wet cells, spend the extra money elsewhere and worry not.
