Just as advertised.
I shoot rapid fire with my D700 so freshly charged batteries are a must. This charger is quick and efficient.

I misplaced my original charger and ended up missing some great photo opportunities since my batteries were all dead. I ordered a new one from Adorama. Prices are competitive and I am always satisfied with the attention that my orders receive.
I needed this for re-calibrating some used batteries that I purchased. Couldn't do that with the aftermarket charger that I had.
I bought this to add an EN EL 4 battery and the BL-3 Battery Chamber Cover , to my Nikon MB D10 Battery Grip For My D700. I am very pleased with it all, a faster battery that does more high speed shooting , and long bursts between writing files to CF card . The battery itself lasts much longer and this charger charges very quickly ..I am very pleased
I use this to charge batteries for by MB-D10 camera grip. Amply does the job. A good investment.
Charging the EN-EL4a for use with my D700. Quite expensive, but for the money it's quick and has more advanced progress readout. If it ever needs to be done, I'll be able to recalibrate the charging scale as well.
This is another reliable Nikon product.
Never needed to recycle the battery. But it is a great option to have.
Good Charger as Far a chargers go I guess. Pricey, but what are you going to do.
Got this for my EN-EL4a in my MB-D10 for D300/D700. Cheaper than the double charger, which I didn't need. Perfect for my needs.
would be nice if would charge other batteries or could plug directly into the wall
