I have stopped offering NiMH conversions until a better selection of higher
capacity batteries are developed.
Anyone who bought NiMH cluster from me in the last 6 months and have found
(as I have) the performance shortcomings, I'll accept the clusters for
credit ($42) toward the original Olympus nicad cluster ($70).
