A fully charged EN EL4 having stood for a few days I checked just now reads 12.65V, another battery fresh off the charger reads 12.5V.
The actual cell voltage is determined by the chemistry of the battery. It's the capacity and flow which can vary according to design. The more active chemicals you can stuff into a given cell the more capacity the battery will have, within certain limits.
Prompted by this thread I have ordered an EN-EL4a from the eBay supplier in Preston, he answered an enquiry promptly and was helpful so I ordered one.
