I performed some measurements that may interest you. The WP 34S will run reliably all the way down to 2.35 V.

Unfortunately that value is completely irrelevant and totally useless, for the very reasons Marcus explained. Depending on the particular battery's internal condition, when its no-load voltage becomes that low, a very small load can cause it to decrease precipitously. The calculator cannot tolerate the slightest power interruption, and will reset at about 2.33 V, even if it goes that low for an instant.
