how much voltage drop is normal for a agm 12v battery or any battery if it is fully charged and connected to nothing?

Don, the Lifeline factory manual claims a 31 rated at 110 ampere hours can safely swallow a 500 ampere charge rate. This is what is giving me the willies with those cheapowatts, not a misprint here, the text reads five hundred amperes, 500% of 20 ampere hour rate,
Isn't that is where a temp-comp charger is needed? Doesn't that allow the charger to automatically monitor battery temp and control Voltage?
Why would there be any need for 'the willies' whith an automatic temp-comp charger?
Optima says their batteries can be charged with unliminted current at 15.6V so long as the battery is held under 125F until the charge rate reaches 1A. Isn't that a prescription for a temp-comp charger? What that says to me is that if the temp reaches 125F, the charger should automatically reduce Volts to maintain 125F and that would determine the actual current limit.
