The NiMH battery technology keeps improving.  As with many things, it's
most economical to buy somewhat below the current state-of-the-art, so
at the moment the 1500 - 1700 mA-hr cells are usually the best deal.
However I wouldn't use any NiMH cells for an EPIRB since they slowly
discharge when left unused for long periods.  They're fine for a month
or so, but the capacity decreases substantially with longer storage.
