(More customer reviews)I bought this battery as a spare for my new Nikon dSLR camera. On first inspection, the battery appears to be built well, and it functions well in the camera. However, right away I noticed that the capacity wasn't as large, just by monitoring the battery indicator on the camera as I was taking pictures.
Being the Electrical Enginerd that I am, as well as electric RC pilot, I happen to have a very smart LiPo charger on hand. I rigged up an adapter to test the original Nikon battery, as well as this "off brand" spare. Here are my results:
Nikon EN-EL9a
Rated Capacity: 1080 mAh
Measured Capacity: 990 mAh
Maximal Power (Power 2000?) EN-EL9
Rated Capacity: 1800 mAh (yeah right)
Measured Capcity: 675 mAh
Both batteries were measured for both charge and discharge current capacity and the two results were averaged. The Nikon battery measured pretty close to it's rated capacity, while the "Power 2000" battery came in at nearly a third of IT'S rated capacity, and approximately two thirds the capacity of the Nikon.
I am disappointed at the misleading package markings on the knock-off battery, however, considering that the battery cost less than the shipping and handling charge, I can live with it...especially since I bought it as a spare. Actually, considering how cheap it is, I think I will now use it as my primary battery and keep the Nikon as my spare, I'd rather use up the limited LiIo charge cycles on the cheap battery!
My recommendation is to buy two of these at a time, so you're only paying one shipping fee (if it works that way?). That will reduce the per-battery cost and compensate for the reduced capacity of these batteries at the same time.
