Q: 5. What are the recycle times when there are 4 Ni-MH batteries in the battery pack? When there are 8 batteries?The Product Highlights list at the top says, Fast Recycle Times Up to 1.24 Sec. The product description below says, Recycles as fast as 1.92 seconds (with 4x AA alkaline batteries in flash unit and 8x Ni-MH batteries in Compact Battery Pack).So is it 1.24 seconds or 1.92 seconds?

A: First the way battery packs work with a SB-900 and SB-910 you need the AA batteries in the flash and you need eight in the pack. It cannot be used any other way. The fastest the flash will recycle can be as fast as 1.92 seconds. The 1.24 is a web error.

Q: 8. Will this work with the Nikon SB-700 AF Speedlight? I know the specifications don't specifically lists this flash, but I'm not sure why it would work on some and not others in the Nikon line of flashes.

A: I have this battery pack, and it does not work with the Nikon SB 700 Speedlight. The Nikon SB 700 does not have a spot to connect the cord from the battery pack. I hope that helps! We have the Nikon SB 5000, and it works great with the battery pack!
