Hello, I wonder, how an OPTIMALES charging of lead-acid batteries AND AGM should be possible between the often wide capacity data of the respective charger (e.g. 14-160Ah)? Is it not generally known that a lead-acid battery with a max. current of 10% of its capacity should be charged, whereas an AGM needs a significantly higher charging tom by the 25-35% of the capacity, in order to be optimally charged or not damaged? charging when the main charge (BULK) ALWAYS with the fixed maximum current is done ? From my point of view, this is always a compromise and does not necessarily extend the battery life of both battery types equally. Man(s) is also maximally confused that one can often unlock a RECOND function IN CONNECTION with AGM. In fact, the mode is intended only for certain lead-acid batteries, which can be charged with a higher voltage of 14,7V… Greetings, Martin
