Notes on Batteries
•
Because flash consumes a large amount of battery power, batteries may not
operate properly before reaching the end of their stated lifespan or the number
of charges/discharges as specified by the battery manufacturer.
•
When installing batteries, turn off the power of the Speedlight and never reverse
the polarity of the batteries.
•
If the battery terminals become soiled, remove dirt and smudges before use, as
this may cause malfunction.
•
Depending on battery specifications, when batteries become hot, the SB-910's
safety circuits are activated, cutting off power. This often occurs when the flash
unit is operated repeatedly. Battery power will recover when the temperature
returns to normal.
•
Battery power tends to weaken as the temperature drops. It also gradually
decreases when batteries are not used for a long 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 the recycling time.
•
Do not store batteries in locations subject to high temperatures and high
humidity.
•
Be sure to read the user's manuals for your rechargeable batteries and battery
charger for detailed information on how to handle and recharge the batteries.
•
Never attempt to charge batteries that are not rechargeable batteries, as they
could explode.
