At least you accept that the NiMH tech is pathetic at best.
The one that I am using is 3.2vx2 - well within the 10% generally accepted voltage tolerance level .
I've still never seen a manufacturer create an user device for RCR-V3, and you still have not presented me with a single microelectronics user product that takes one by design (only stating who makes the batteries).
The RCRV3 is the renewable substitute of the not quite environmentally friendly CRV3. A device (and there are many) designed for CRV3 or 2AA batt can also be powered by RCRV3. I have to agree that the voltage variance (of some fly by night vendors without an industry wide standard ) may not be acceptable . That was at least the case prior to the launching of regulated RCRV3.
The "proprietary Li-Ion" reality of the world isn't a "trend," it's the reality as no vendor is going to certify their products for the great variances in Li-Ion implementations. There is no standard Li-Ion reference at all, and that's why.
There may be a reality or trend . Whatever. But it does not alter the fact there are a lot of users worldwide prefering an insignificant overvoltage (under 10%) than a major undervoltage ( 6V cf 4.8V).
Oops. My apology to the OP as we seem to have hijacked this thread
