Is flooded equalization charge always timed?
I have (2) of the 6v interstate costco batteries. Would like to do an equalization charge on them. Using the Trojan users guide for directions. Trojan is saying to equalize for 2-4 hours. But it a...

While following a recipe perfectly is of course ideal, often ideal cannot be easily achieved. The goal of EQing a battery is maximum specific gravity with minimal acceptable abuse.
I can get batteries there without following the recipe exactly, I just did so yesterday on what 'might' be the exact same batteries as Wopachop, and these batteries will get drained to 10.5v as they work for a living and their owner simply don't shiv a git. His converter is an Iota dls-45 I installed some 5 years ago. I tell him to plug in for 3 days after an outing then hit the disconnect I added. The interstate gc2s are 3 years old and yesterday was their first watering afaik, and their second EQ besides when i first got them.
The screwy31 has been walking dead for year and years now, often ignored, and still going. The concrete under it is surrounded by a dam of baking soda and chewed away inside that barrier. I bring it up as an example that perfection of process can be skewed pretty heavily, and still yield more than acceptable results.
I took the screwy31 out of my rig in june of 2015, and it mostly sees a 100 watt south facing panel daily and charge controller that attempts to achieve absorption voltage for 2 hours a day. It provides upto 30Ah nightly 5 days a week.
Its charge efficiency factor is horrible, but solar is free, so i dont care.
It's self discharge is likely 2% a day or higher. also not a factor.
It got some attention yesterday only as I had my meanwell unscrewed from my rig's electrical cabinet door and a 2/3rds a gallon of distilled handy.
When it becomes a 10.5v battery, I'll likely core charge it toward a new high $$ AGM, and my equal aged and impressive Northstar-27 AGM will assume its place in workshop duty even if it is still a viable dual purpose cycler and engine starter at that time.
