Charging Lead-Acid batteries in parallel is not a problem, but a larger battery charger that feeds up to 6A, when equally divided by your 3 batteries of 9Ah, would give 2A/battery, in the best case. Sealed-LA batteries maximum charging current usually is 10-20% of rated capacity. For a 9Ah, I_max = 1A ~ 2A.
But as the battery gets charged up, its back voltage increases and it will go higher than the 12.7v which is typical of a fully charged lead acid accumulator. When the battery charger is first disconnected from a fully charged battery, there is for want of a better way of describing it, some surplus leccy left on the plates and the voltage reading is higher than the 12.7.
The battery temperatures increased slowly due to the 20.4Kg mass of 68Ah AGM lead-acid battery although the heat capacity of the AGM lead-acid battery is smaller than that of
I am currently running a pilot where I have a 12V 5A regulated supply connected in parallel to the load (< 1Amp) and 12V 7AH sealed lead-acid batteryWhile the setup actually works flawlessly, the flaw is that the battery is constantly being maintained at an undercharged state of 2-2.05V per cell which translates to approx 50% charge level.
