[QUOTE="nickt, post: 538606, member: 4923"] I don't have that flash and I only have the old original eneloops. (they never die). But I will say this. The mah is an indication of stored energy, but not necessarily how fast that energy can be delivered. I would think a 2000mah and 2600mah MiMH cell would deliver at pretty much the same high rate. Think of a water tank and hose. The 2600 has a bigger tank, but same size outlet hose. NiMH has fast delivery in general regardless of mah rating. Not as fast as a Li-ion battery, but certainly faster than an alkaline. So the 2600mah will give more flashes but should recycle the flash just as fast as a 2000mah. In comparison, a regular alkaline may be 2800mah. It cannot deliver the energy as fast a a MiNH though. It has a much smaller 'hose'. It in fact will not achieve its rated capacity if drained at a very high rate. They are best for lower drain devices.
