Customer Reviews

A preference for the name brand battery
I liked the price on amazon, so I bought this Nikon brand battery for my new Nikon D40x 10.2MP Digital SLR Camera with 18-55mm f/3.5-5.6G ED II AF-S DX Zoom-Nikkor Lens. So far, so good. The battery charges fairly fast and lasts a long time.

I'm a firm believer in having at least one extra rechargeable battery for a digital camera. If you take a lot of pictures, you have a good chance of your battery running low while you're out and about. If you don't use the camera often, you might take it to a special occasion without realizing that the battery's getting low. In either case, having a spare fully charged battery will help you avoid the frustration of having a dead camera at the wrong time and place.

I'm okay with paying a few extra bucks for the Nikon branded battery, based on my experience with two "no-name" rechargeables I bought a few years ago for my Nikon Coolpix 7900 camera. The "no-names" cost less than the Nikon brand battery. They charged up and worked just fine at first, and I rotated all 3 batteries through the camera, with roughly equal amounts of use and recharge cycles for the batteries. All rechargeable batteries eventually lose their ability to hold a charge, after going through a number of charge/discharge cycles. In the case of the Coolpix camera, the original Nikon battery outlasted both of the "no-name" generic batteries.

So based on my experience with those batteries, I'm sticking with the Nikon brand for the extra battery for my D40x, because I expect it to last through more charge/discharge cycles over its lifetime than a generic (and cheaper) equivalent battery.

BUY THE NIKON BAG KIT INSTEAD
If you are looking for a spare battery for your D40, I recommend you purchase the Nikon accessory kit instead (comes with a great Nikon camera bag, spare battery identical to this one and a photo guide). It barely costs more than this battery alone and you will get the bag for almost nothing.

The only backup battery I would buy
I use this in my Nikon D60. The only reason I didn't give this battery 5 stars is that it is a bit pricey. Having said that however, I wouldn't buy any other battery for something as important as my digital camera. I've tried knock-offs before and have been very disapointed. This official Nikon battery however has not disappointed at all. It has a very good life and I never worry in a critial situation.
