Charger/converter not charging batteries/how to test?

Make sure the new converter can be made to hold voltage at the bulk setting during abs; preferably in the 14.4-14.8v range. Most converters drop their voltage to 13.6v "normal", once this setpoint voltage has been reached; which is usually in the battery's 75-85% soc range; still a long ways from full. This results in less than 100% soc, overall, as well as lower sg and resting (ocv) readings... even though the converter may say the battery is full, it is not.
