Odyssey/DHP is looking to be the AGM I buy.
Check out this chart taken from their charger PDF
http://www.odysseybattery.com/chargers.htmlHere it says My current Schumacher sc2500a charger is adequate for one single 65 A/H group 65 battery but only when on The 25 amp setting. It is not adequate for the group 31 battery.
http://www.odysseybattery.com/documents/ODYSSEYApproved12VChargers_000.pdfFrom this I infer that 3 group 65's should be fed no less 75 amps initial bulk current for 'proper charging' This would be 0.46c minimum initial current. As if my 200 watts of solar could ever approach this current level.
Unlike other AGM VRLA batteries, the ODYSSEY battery is capable of delivering up to 400 cycles
when discharged to 80% DOD and properly charged
That quote was taken from this PDF:
http://www.odysseybattery.com/documents/US-ODY-TM-001_0411_000.pdf Which converter can best meet these "proper charge" requirements?
Apply 75 amps initially, hold 14.7 for 4 hours then float at 13.6.
Any that can do it on a 15amp AC circuit?
What about floating them at 13.2 if I have to? What could happen?
Wonder how much flexibility there is in these currents and voltages. how close is close enough do you think?
As I type, my odyssey approved Sc2500a is holding my flooded 27's at 13.6v, and feeding them 0.9 amps to hold them there, on the AGM 25 amp setting.
