I did finally replace my Greyhawk, Gp 27 wet cell with a Gp 27 AGM. The AGM doesn't seem to hold a charge very well, shortly after unplugging, before starting the engine, the low voltage beeping begins on my CO/Propane detector. I have had to remove the detector due to the beeping irritation.
Haven't been able to take the time to check battery voltage at the posts (in storage now).
When plugged in to shore power the Xantrex reads 13.6 volts. Is this too low for an AGM? I have heard that AGMs require a higher charging voltage.
Where is the Greyhawk battery charger located? And can the charging voltage be adjusted up? Does it have an AGM setting?
