I remember one team saying they did so much off season stuff they used up 10 batteries a year. I'm not going to debate if that's due to misuse or what. Regardless, their life span is also longer and can result in long term savings to a team.
At work, we expect a SLAB to last 2 years if not heavily cycled. In FRC I have found we will get 3 or 4 seasons. At work, we expect a lithium to last 5 to 10. Even with the increased up front costs, this can yield substantial savings in the long run.

10 batteries isn't outlandish. We usually lose 4 or 5 a year, and I can remember a couple years ago when we did a lot worse. Some of the team were hot-cycling batteries to complete discharge at a week long fair demonstration without realizing what would happen. We lost around 10 that year.
