Well nearly , the 2 negatives joined and 2 epitaxial diodes (avoiding mutual
discharge possibility) from the positives commoned and then on to the
memory, is there some circuitwise reason? Both cells are from the same batch
, so not as though "all your eggs in one basket" circumvention.
Is the chemistry of this type of cell odd? 3V cells originally , could be 20
years, but removed from the pcb and out of circuit still 3V. Put 150K across
either cell and it drops in voltage to 2.9V or so compared to just DVM
loading. Remove and immediately recovers to 3V.
Tried 5K6 over for 12 hours , dropped to 2.6V , measured a few minutes ago,
removed the R and immediately recovered to 2.9V, I expect when I get back to
it , it will be back to 3V with just DVM load
