Nikon EN-EL4a battery and BL3 battery chamber cover $65 Both of these are genuine Nikon products and were never used as I decided to use AA's in my D700 instead. As such both are mint and both have the original boxes ( I have the box for the enel4a, it's just not pictured). While the BL3 is just for the D700 the battery can be used in a variety of Nikon DSLR's and costs $120 new at either Adorama or B&H. Shipping and handling are extra. Paypal or money order preferred.
