Use four size-AA batteries.
Recycling Time and Flash Count
Battery Type
Size-AA alkaline batteries
Based on a new set of batteries and Canon's testing standards.
To avoid overheating and degrading the flash head, do not fire more than
20 continuous flashes. After 20 continuous flashes, allow a rest time of at
least 10 min.
Use a new set of four batteries of the same brand. When replacing the
batteries, replace all four at one time.
Using size-AA batteries other than the alkaline type may cause improper
battery contact due to the irregular shape of the battery contacts.
Size-AA Ni-MH or lithium batteries can also be used.
