Scenario 1:
Someone asked me to repair a golf cart style battery charger. I found there was nothing wrong with the charger itself. The charger was not turning on because it didn't see its minimum cut-on voltage because the batteries were too dead.
Q1:Why do they design a charger with a cut-on voltage that is so high that it won't recognize dead batteries?
Scenario 2:
Large batteries used in forklifts and similar equipment use scr type chargers that are able to detect voltage and battery capacity and automatically adjust the charge program to suit the battery that's connected to it.
Q2: How does it detect the connected battery capacity (in ah), just by the 2 wire charging leads? I may have a 36v battery with a capacity of 510ah, and another 36v battery with a capacity of 750ah. How does it know the difference?
Q3: If I have a 48v battery that is ran down to 36v how does charger know its a 48v battery and not a charged 36v battery?
This 2nd type charger is an Ultracharge model multi-volt charger made by Amtek. Batteries don't have the optional memory chip (bid module) that the charger talks to. Just the pos and neg charging cables.
