For sealed AGM batteries
Bulk: 57.6- 58.4
Float: 54 - 55.2
Somehow thought you had FLA
Here that is....
Lead Antimony Flood lead acid.
Bulk/absorb 58.8V daily
Float 54V. Daily
Equalize 64V never, -Ha, yes its necessary but only while watching whats happening with SG meter etc.
Lead Acid batteries come in several flavors and they are ALL different. So starting there, you said wet cell or FLA, assuming Lead antimony type since most deep cycle like Trojan are this type.
Then there is the "character of the battery" through the life of these batteries their needs can change so you need to watch behavior and adjust accordingly. Some dont like higher voltages and boil water instead which can shorten life. So good care of FLA is not "one size fits all"
If they are new and true "deep cycle" bulk/absorb starting point is 58.8V.
Meaning charge with available amps staying below max battery charge current until voltage rises to 58.8V then maintain that voltage for absorb time until current drops significantly. Then terminate charge.
Record specific gravity, and ending current.
If your batteries are taking a fair amt of current and the voltage never builds to 58.8 then maybe 57.5 is the right number.
Try to hit the sweet spot, dont push them too hard too high voltage nor too soft and monitor capacity and SG. Equalize can bring capacity and SG back up a bit but you also corrode the positive electrodes by the harsh treatment and so loose life that way. Sometimes you cant win no matter how good you treat em then other times.... true story, the auto charger on a golf cart failed to terminate. Ran all weekend, there was literally no water left in them. I grabbed a new 3Gal jug of drinking water, almost all the water fitnin the 6 batteries. That was over a year ago and the batteries still act like new, nearly 4yrs old now. I dont expect them to last 10 years but they see the worst abuse imaginable and no signs of weakness yet. By the way those perform i would say daily hard work is better than sitting idle. Seems like deep FLA batteries that get treated soft become weak. I will look at brand name and update.
Everyone has different ideas about how to treat lead acids. Many on this forum know more about it than me so consider the sources and the environment. Cold is higher hot is lower for example.
By tbe way, wheres Doc Hubert? havent heard from him in a while. hope he didnt bolt the hatch down yet

. Those politicians gettin on everybody's nerves lately. Least our supreme court shot down their latest scams so we dont hav to wear diapers on our faces at work anymore.
All the best, have fun!
