How'd the Woodstock C's survive?

After my own 29C bought at auction and perusing this site, I now realize that recharging the 25C and 29C would cause these calcs to be lobotomized beyond functionality because of the charging damage. But, how was it that the original 1970s owners would still have a functioning 25C or 29C?

Thanks

They can be recharged no problem. They are only damaged if you operate them from wall power without a battery, or with a defective battery.
