Viability of an ML 1220 rechargable battery for RTC | CMOS (11th gen)

Ergo, the non-rechargeables are much better for this use case and are actually more sustainable in the long run.

That they drain is not an intentional design decision. Under normal circumstances, where this draining wasn’t an issue, they would be the better sustainable solution. I doubt very much that it was intentional that the RTC batteries drained in a few weeks. This is what I mean.
