If your batteries are dying that fast, you’re doing something wrong.
You’re saying that data centers are replacing batteries constantly…just imagine the labor costs on that (and the down time), not even considering the material cost.
I work in enterprise, and have never heard such a thing. Even my friends in SMB routinely replace UPS’s at the 5-year mark, the same time they replace servers. They rarely replace batteries, at all, it’s so rare that it’s notable.
