For top charging and equalization use the FIVE PERCENT OF TOTAL AMP HOURS FORMULA. You have the two best analysis staring you in the face....
HYDROMETER SPECIFIC GRAVITY
HOW VIGOROUSLY or not are the cells bubbling?
TRENDS AND TENDENCIES
You can not manage flooded lead acid batteries without an accurate baseline of FIRST determining how voltage and amperage REACT to specific gravity readings. Think of it as going a million miles into space and then try and determine WHICH WAY IS UP...
Each entity of construction. Percentage of antimony, whether hybrid plate construction is used (calcium negative plates) or a myriad of other fundamentals are used or not determines the characteristics of your battery.
What the battery shows via instrumentation are the clues. Clues are dirivitives of specific gravity as measured with a hydrometer.
Managing a flooded lead acid battery solely by a rudimentary manual issued by the manufacturer is a fool's errand. Got it?
Far too many discrepancies between reading and reality. Electro chemistry is only understood precisely by someone willing to anchor baseline numbers and only the can they manage for awhile management via instrument numbers only.
Trends And Tendencies.
Manufacturers publish estimated number of cycles yet less than one half of one percent of users approach within forty percent of that number of lifetime cycles.
Look at the hydrometer reading FIRST and instrument readings SECOND.
Having an adjustable charger like a Magawatt makes this easy. A preset smart charger's prime directive is to argue and ignore reality.
