Notes on batteries
Warning
m Batteries shall not be exposed to excessive heat such as sunshine, fire or the like.
m Dry batteries shall not be subjected to charging.
m Do not expose the SB-80DX to water as this may result in electric shock or
cause the unit to catch on fire.
l
Usable batteries
m Use four AA-type batteries (1.5V or lower) of any of the following types.
nHigh-power manganese batteries are not recommended.
nUsing an external power source (p. 94) increases the number of flashes and provides
faster recycling times.
Alkaline-manganese (1.5V) battery
m Non-rechargeable batteries. They should not be charged in a battery charger.
Otherwise, they may explode.
Lithium (1.5V) battery
m Non-rechargeable batteries. They should not be charged in a battery charger.
Otherwise, they may explode.
nDepending on battery specifications, when the battery becomes hot, the safety circuits
are activated, cutting off power. This often occurs when the flash unit is operated in the
repeating flash mode. Battery power will recover when the temperature returns to normal.
NiCd battery (rechargeable, 1.2V) / Ni-MH (rechargeable, 1.2V)
m Rechargeable batteries. Before recharging the batteries, be sure to read the
instruction manuals for your batteries and battery charger for detailed
information on how to handle and charge the batteries.

Notes on handling batteries
m Because flash consumes a large amount of battery power, rechargeable
batteries may not operate properly before reaching the end of their stated life-
span or the number of charging/discharging as specified by the battery
manufacturer.
m When replacing batteries, replace all four batteries at the same time. Do not
mix battery types or brands or use old with new batteries.
m When installing batteries, turn the power of the Speedlight off, and never
reverse the polarity of the batteries.
mWhen the battery terminals become soiled, remove the dirt and smudges
before use, as this may cause a malfunction.
m Battery power tends to weaken as the temperature drops. It also gradually
decreases when batteries are not used for a long period of time and recovers
after a short break following intensive use. Be sure to check battery power
and replace the batteries with fresh ones, if you notice any delays in recycling
time.
m Do not store batteries in locations subject to high temperatures and high humidity.
