When the D4 was introduced the EN-EL18 had a lower capacity than an EN-EL4a, supposedly to meet new legislation in Japan relating to energy density. The subsequent iterations of the EN-EL18 have raised the capacity well above that of the EN-EL4a so either the original reason was a fudge or the law in Japan has changed again. The shielding on the contacts looks to be the same on both but investigation reveals that the EN-EL18 contacts are about 1/2mm deeper inside the battery. With an adaptor plate the MH26 can charge both battery types, as well as some Canon batteries for the EOS1D series.

I don't have any "dead" EN-EL18s all six show as near new. I thin that after working in avionics for 45 years I can probably recell a battery!
