“That all being said, properly maintained battery packs in fleet carts tend to last about 4-6 years while private owners tend to get about 6-10 years out of their battery packs.”

That site is talking about batteries being used in actual carts, not with solar panels, but I imagine the maximum lifetime won’t exceed 10 years either way.

Proper management of a solar power battery should provide at least 10 years of service but with proper care can last 30 years. The trick here is to oversize to begin with. Never use more than 25% of your storage and your batter will hardly know it was used. There are still a few maintenance tricks to keep sulfides down but it can be done.
I personally believe you should only get a battery that was designed for very heavy use, I only recommend tow motor or lift truck batteries. They are huge, unwieldy but can last a lot of years with good management.
