Isn't any portion of a plate which has dried out, permanently damaged
and unchargeable? The rest of the "dead" battery may be rechargeable,
but the battery's capacity is reduced.




Nope. It just lost contact with the electrolyte, so is unable to be in the
current stream to recharge. As electrolyte is recovered in charging, it
gets deeper, so we don't want to fill a discharged battery because it will
overflow by the time charging has recovered it.
