Li-Ion Battery for Nikon EN-EL20 / ENEL20 / 7.4V Lithium Ion battery with 800 mAh for Nikon digital camera 1 J1 / J2 1 (electronics)
I bought this replacement battery, because the original battery by Nikon but are quite expensive. Consumption of J1 is relatively high, so I wanted to change more than one battery. After some time of use, I can not tell the difference from the origin
