Type of battery Recycling time Remedy Alkaline-manganese More than 30 seconds Lithium More than 10 seconds Replace Nickel More than 10 seconds Ni-Cd (rechargeable) Ni-MH (rechargeable) More than 10 seconds Recharge If extremely exhausted batteries are used, a strange sound can be heard caused by the flash head zooming back and forth even when the SB-800 is turned off. In this case, replace the SB-800's batteries even if an external battery source is used. t External power sources Using an optional external power source increases the number of flash firings and provides faster recycling times (p. 113). 19
