Yup. I did so after seeing what happened after 14.4 was discontinued and 13.4 float was employed. The amount of amperage at 13.4. It decreased within 6-minutes. But temperature compensation enters the fray. It's warm here.
If folks would spend time during the charging process and absorb voltage and amperage values, correlating the two values becomes easy. But for ease, nothing equals an amp hour meter, plus factoring amperage and voltage.
Wanna get fancy, measure current with a multimeter after the battery has been floating for a day. The old Trends & Tendencies bit. Float the battery after a guaranteed full charge, let it rest for a day, enable bulk and the amperage should spike then instantly react and rapidly sump to full charge state. A new battery will take "X" amount of amperage to float correctly and if that value changes you'd better find out why. It'll change as the battery ages, but that's a very slight decline and rather linear until failure with the battery occurs, capacity lessened to 80% or less.
A balance between sulfation and plate erosion can be established.This is the definition of truly floating the battery. But chemistry imposes and even an AGM benefits by two-month cycles of top charging. I really do like the periodic goosing with 14.4 volts while monitoring amperage. It's a real BS detector.
