And what fine print is that sir? Forgive me for bein lazy, but I am not readin a whole dang manual just to find out your point. Care to give us the cliff note version?
Two big points. The three step charging protocol is much different than what a standard regulator provides. The other is operating temperature, and how that declines battery life. To correctly employ the battery, and achieve the benefits over a standard battery, involves relocation out of the heated engine compartment, a specialized regulator that provides voltage, current, time, energy, and battery temperature in the controls. AGM batteries are not dry, they still have electrolyte in the glass mat, and a valve system to help let gas out but retain moisture. I can go on, but to get more RTFM. Results are going to vary, by where you live, charging and usage. So you can buy an expensive battery, and buy an expensive marine AGM regulator and see if it works. You might find conventional batteries over the same time interval are more economic. Conventional batteries do not provide bragging rights.
