AGM Settings

[mikewess]

I had my 2013 Palazzo hooked up to an outlet at home where it did fine charging to full prior, but I noticed that it had discharged somewhat. Found out it was a tripped breaker at the house, so I fixed it. But I happened to check the settings on the controls and found that it was set for flooded batteries. Now this would be ok a year ago, but I changed them out last year to AGM's. There is a setting for "AGM1" and also for "AGM2". Should I change the setting to one of these, and if so, which one? How do I tell what type I have? And shouldn't the dealer have done correct setting when installed? Is the only difference in the setting the charge rate?

AGM1 (for Lifeline AGM batteries), or AGM2 (for East Penn/
Deka/Discover/Trojan AGM batteries)

on magnum its AGM1 is trojans....all others use AGM2
thats how magnum told me to set mine up

Agm batteries are basically a deep cycle battery with higher amps, but they do have to charge at a slower rate(Amps) then flooded.

Same on the Tuscany and the way I have my Trojan T105 AGM's

Trojan list the recommended bulk charge voltage for AGMs as 14.1 to 14.9 volts. Magnum list the bulk charge voltage of 14.2 for AGM #1 and 14.4 for AGM #2. Lower charge voltage is always better as it allows more time for the recombination of the water ions formed during discharge. Of course the lower bulk charge will mean a longer charge time. As best as I can tell the absorption voltage is the same as the bulk. The float voltages are the same for both AGM settings.

Lots of info under the T105 download link

If you are considering upgrading or exchanging batteries these are excellent quality
