For reference review the attached Interstate battery link;

https://www.intechtrailers.com/image...nce-Manual.pdf

Note the bottom left of page 4. As you can see one complete discharge (100%) reduces the number of charges you could get from a new battery by almost 90%. To me that is effectively "ruined". This happened to me with 2 new Interstate batteries when I left my trailer at the dealership for a couple of weeks; they pulled the breakaway pin and killed them both. I provided them a copy of this chart and demanded 2 new batteries and they complied.

Being aware of battery usage, state of charge and regular maintenance is very important in getting the best service from them.
