Once the battery is fully sulphated (worn out) you can rejuvenate it using alum, alum batteries are more resistant to high dod but are "saggier"
Making a new alum battery would be a waste of a good battery.
One guy on this forum ran worn fla batteries he converted to alum got from a scrapper in his ev, cheap but definitely a tinkers setup.
