Three original Nikon Rechargeable Li-ion Battery EN-EL 3e are with me for 5 years in a Nikon D80 and for about a year in a D300s in use. With a total of well over 100,000 images. Average of at least about 1,800 sports and other pictures can be taken in continuous use per charge. Excluding camera flash, if necessary most of the Nikon SB-900 flash is used. The amazing thing is that between the oldest battery and the moderns is practically no loss of performance is observed. With the Nikon D80 had to be replaced after about 80,000 images of autofocus and the shutter button, the battery lasts until today with full power. Nikon stelbst writes in advertising: "Lithium-ion battery with high capacity (7.4 V, 1500 mAh) The battery can be recharged at any time without a memory effect occurs.." This I can absolutely confirm in practice. Overall, for me there are 4 batteries for the two Nikon cameras in use, 3 originals and a clone, who is also good. However, I will continue to use only genuine Nikon rechargeable batteries. The price differential (15 to 20 euros) is well founded and durability through higher quality of the original (50 to 60 euros current price). The even cheaper clone are worth nothing and soon make flabby, which occupy the reviews here in the forum. From me, there are five star and a strong buy recommendation for the original Nikon battery.
