About Batteries
New batteries
Purchase the newest (freshest) batteries possible.
Temperature
Battery life ratings are based on operation at 20˚C (68˚F).
Especially at a lower temperature, battery life is shortened.
Keep spare batteries and if possible, use NiCd batteries.
Continuous use
Batteries are drained more quickly by continuous use than
by intermittent use.
Storage
Store batteries in a cool, dry place, below 20˚C (68˚F).
Battery brand
Do not mix battery brands or models, or new and old batteries.
Disposal
Do not dispose of batteries by burning, and never disas-
semble batteries.
NiCd batteries
Compared with regular batteries, NiCd batteries offer a faster
recycling time and greater efficiency at low temperatures.
Before charging NiCd batteries, thoroughly read the
instructions for the batteries and battery charger.
Batteries with a “+” terminal that exceeds 6mm (0.23”) in
diameter cannot be used.
DC Units SD-8/SD-7
Nikon DC Unit SD-8 or SD-7 can be used as an optional
external power source to enhance flash capacity and pro-
vide faster recycling time.
To use the DC Unit, connect its power cord SC-16 to the
SB-26’s external power terminal. Even when powered with
the DC Unit, the SB-26 still requires batteries inside the
flash unit. Do not remove the batteries.
In continuous shooting with the DC Unit, to prevent flash
head deterioration caused by heat, do not exceed the maxi-
mum number of flash listed below. It is recommended to
rest for more than 10 minutes after firing near the maximum
numbers.

Power Bracket SK-6
Enables you to use your SB-26 as a grip-type flash. In
addition, by installing batteries in the SK-6, you can use it
as an external power source for SB-26. If SB-26 is already
powered by the SD-7 or SD-8, the SK-6 can be used as a
secondary external power source.

Warning
• Batteries shall not be exposed to excessive heat such
as sunshine, fire or the like.
• Dry batteries shall not be subjected to charging.
