This Wasabi Power dual battery charger replaces the Nikon MH-26 and the MH-33 to fully charge the Nikon EN-EL18, EN-EL18a, EN-EL18b, EN-EL18c, and EN-EL18d batteries. It will charge two batteries sequentially (one after another) so that you have a fully charged battery ASAP. The MH-33a charges the Li-Ion batteries for the D4 and D4S cameras and can also be used with the MB-D12 or MB-D18 battery grips.
