Guide value
1battery charge
On paper, the battery in your camera is enough.
A guide value, not a guarantee: based on approx. 1200 shots using the viewfinder per battery charge (CIPA figure from Nikon for the D810A, a standardised comparison test) or approx. 40 minutes of video (CIPA, HD video (figure from Nikon USA for the D810A, the same as in the D810 manual)). According to Nikon, the actual runtime depends on the conditions of use; we have not measured these figures with Baxxtar batteries.
