•The above specifications are based on Canon's testing
standards.
• Using size-AA nickel-hydride batteries will yield only about
70 to 80 percent of the flashes (1550 mAh at full output)
obtainable with size-AA alkaline batteries. The recycling
time will also be about half the time with size-AA alkaline
batteries.
