"Anyone seen specs for the V2's EL21 battery?" Fri 26-Oct-12 06:18 PM by kenuck
Several people have said the new battery is smaller than the V1's EL15 but I can't find any specs on it, other than a rating of 310 shots on the V2 vs 350 shots on the V1. However the V2 would probably include some built-in flash usage so the results not really comparable.
Nikon's battery numbering system not really logical but they're generally higher voltage and/or Ah as the numbers increase EL12, 14, 15, 18 (J1's EL20 the exception)
