Kastar 2 Packs EN-EL9 Compatible Battery Replacement for Nikon EN-EL9, EN-EL9a, EN-EL9e Batteries and Nikon D40, D40x, D60, D5000, D3000 Cameras, Nikon MH-23 Charger

These are replacement camera batteries and are a great value I paid more for one at a camera shop but it was a different brand I can not speak to how long they will last yet they are rechargeable. they fit my charger no problem and fit my camera as well so far so good easy to use unless you try to install them in your camera wrong will only go in one way I believe they are good quality but will have to let you know more about that after using them longer at this point they hold a charge well so I believe you can say they function as they are supposed too I will more than likely purchase again unless there are unexpected problems with them I don't foresee any but one never knows

works as expected. great battery, good capacity ànd quality.

Very good batteries. Work better than original in my D5000

The value is there, and the performance is pretty much there. I do not get the same battery life with these as I do with my Nikon branded battery. For a fraction of the cost of the Nikon battery, these are an awesome deal. I will purchase them again if I happen to get a different Nikon camera that takes a different size battery. These are too good to pass up.

I needed to replace the batteries for my Nikon D40 (really "old" technology). I bought the two pack because I thought I would need to replace them every few days. I'm still using the first battery (after a month!) and it is nearly fully charged. It's a quality product at a great price.

It works on my Cannon camera that the original battery died on It is functional and the right size st an affordable price!

Both batteries charged without issue and the camera did not complain.

Batteries don't stay charged for long
