[volt-nuts] Old Weston cells

I got my hands on a few very old, unsaturated cells. I figured that they
would be no good after all this time. Just out of curiosity, I measured
them on my 3457A, which hasn't been sent off for calibration yet.

DMM was set to 3 V scale to keep the input impedance high. Room temperature
= 26 C.

Cell #1 = 1.018288
Cell #2 = 1.018236
Cell #3 = 1.018224

I read that when they get below 1.0183 V, they are no good. Is there any
(easy) way to rejuvenate these cells?
