position adjustment, or LCD panel illumination.
• The above data may vary due to variations in battery performance.

Replacing/recharging the batteries
Refer to the following table to determine when to replace or recharge your
batteries, if the ready-light takes a long time to come on.
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)
More than 10 seconds Recharge
Ni-MH (rechargeable)
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).
