My 0.5A/100AH or 2 hours timer is what it is set to. Timer can be set to any value from 1 to 240 minutes. I wonder how many people choose to keep AGM at V Abs for more than 180 minutes.
When it reads 1.5A on controller at V Abs before switching to V Float, it is 1.5A to battery. If fridge is cycling at that moment, the current is +2A, timer takes the authority and terminates Abs in due time or the fridge shuts down and control reverts to current. Alright, not 1.5A to battery - 1.52A counting the propane detector. I know my system, know what loads are on, there are no gremlins or people to do something without me knowing.
I wish my AGM could drop below 0.4A/100AH, but it doesn't do this anymore. What Mex said about AGM being either bad or tolerable is correct, a horrible Chinese cr-ap is what I have.
