Yes they do require equalization, The specs for YOUR battery need to be followed, not some generic specs if you want long life.
My battery sets are different enough that they have different specific gravity specs, and different charge specs and with Rolls-Surette, different specific gravity new and when aged in such as over 6 y.o.
My Rolls-Surette set came out the door in july 1995.......still at full capacity, I use the specs for well-broke in as supplied by their engineer example s.g. out the door 1.277 over 6 y.o. 1.260
Yes they do change over time, unfortunately most batteries die long before that due to LOM lack of maintaince
I did a stint at Alaska Husky Battery in Fairbanks, Alaska where we built batteries that had scorching hot 1.320 specific gravity that were suited for the -70 degrees winter temperatures there.......These were “winter only“ batteries as they would cook themselves to death in the summer, Use them like your studded snow tires, put them in the barn for the summer in a cool spot, They would last 3-5 winters but could not survive one summer. I learned just a bit about batteries over the years.
