Unless Rick has LIFELINE BRAND AGMs, he cannot and must not follow their procedure for equalizing the batteries. Lifeline apparently builds their product differently and every other AGM
naufacturer I have spoken with has emphatically said DO NOT EQUALIZE THEIR BRAND because you will outgas the battery
, perhaps warp it, and certainly damage it.
As for 3-stage charging
, bear in mind there are now MORE SOPHISTICATED charging
routines, such as the continuously varying ones used by MPPT
controllers, which lead voltage by a small amount and then push the rest as amperage. (Subject to thermal sensing and other limiting.) Some fairly respected vendors--like Johnson Controls (JCI) have siad outright that 3-stage charging is now obsolete and the microprocessor controlled chargers will do a better job, faster. #-stage is now the equivalent of "good Dacron sails". You can do worse--but you can also do better.
